Confined, But Not Silenced: Vocal Music of Viktor Ullmann from the Theresienstadt GhettoJanuary 2018 (has links)
abstract: Even in the most despondent situations, the arts find a way to flourish. This research document examines the vocal music that Viktor Ullmann composed in the concentration camp-ghetto of Theresienstadt in German-occupied Czechoslovakia, and the notable aspects of his compositional writing style. Although his opera Der Kaiser von Atlantis has been performed globally, the remainder of his oeuvre has rarely been recorded or performed. Singers often shy away from twentieth-century composers such as Ullmann, with claims that the music is not lyrical or relatable. Perhaps the irregularity of the meter, rhythms, or intervals seem too daunting for many to consider attempting a performance. With Confined, But Not Silenced: Vocal Music of Viktor Ullmann from the Theresienstadt Ghetto, I hope to open the door to music that is both accessible and uniquely beautiful. Not intended as a performance guide, this document aims instead at unearthing the appeal of music that is often perceived as unusual and difficult to perform through analysis that emphasizes relatable aspects of the compositions. By exposing colleagues to relatable music by a composer such as Ullmann, that has not normally been integrated in the canon, the boundaries of standard vocal repertoire can be expanded to include unconventional contemporary compositions. In addition to highlighting specific musical examples, Confined, But Not Silenced focuses on music’s positive effects for World War II prisoners in Theresienstadt. / Dissertation/Thesis / Doctoral Dissertation Music 2018

Viktor Ullmann's Terezín Lieder: a performance guide to songs for soprano or high voiceZabelsky, Jennifer Ann 12 March 2016 (has links)
Viktor Ullmann's Terezín Lieder: A Performance Guide to Songs for Soprano or High Voice is, as the title states, a detailed guide of nine songs composed while Ullmann was imprisoned in the Terezín Ghetto from 1942-1944. This dissertation also proves that although he was incarcerated in terrible and inhumane conditions, Ullmann, among others, was able to compose music highly artistic in style and value. The songs and sets included in this document are "Wendla im Garten" (1918/1943), Hölderlin Lieder (1943/1944), Lieder der Tröstung (1943), and Drei jiddische Lieder/Březulinka Op. 53 (1944).
Included is the history of Terezín before and during World War II, the camp's musical output, and a concise biographical background of Viktor Ullmann's life. A brief biography of each poet or writer (Frank Wedekind, Friedrich Hölderlin, Albert Steffen, David Einhorn, and Zalman Shneour) is given along with a discussion as to why Ullmann chose particular poems and prose. The importance anthroposophy had on his life and his musical output is also explored.
The original text of each poem or prose is given with a poetic translation. In addition, the texts presented in Ullmann's scores are provided with a word for word translation and International Phonetic Alphabet pronunciation guide. A style guide to various elements - e.g. melody, harmony, range, accompaniment, etc. - in each song is also provided in hopes of allowing these songs to be more approachable and accessible. Finally, lists of various foundations dedicated to the life and music of Viktor Ullmann and the Holocaust, as well as Ullmann lieder scores and recordings are provided.

Couplage de type Ullmann : une méthodologie pour la synthèse de matériaux ioniques / Ullmann-type coupling : a methodology for the synthesis of ionic materialsFouchet, Julien 19 November 2012 (has links)
Les liquides ioniques à base d’imidazolium présentent une plateforme architecturale unique aisément fonctionnalisable permettant de préparer des matériaux ioniques avec des propriétés mésomorphes. Dans le but d’introduire des propriétés supplémentaires, nous avons élaboré des composés à coeur rigide étendu. La stratégie de synthèse adoptée passe par un couplage de type Ullmann. Nous avons développé une méthodologie nécessitant uniquement du Cuivre (II) supporté sur zéolithe (Na-Y) et du carbonate de potassium. Cette approche a pour avantage d’éviter l’utilisation de solvant, d’atmosphère inerte et de ligands. Ce couplage a été optimisé en utilisant la technique de synthèse en micro-ondes (réduction du temps de réaction, diminution des sous-produits formés). Après avoir étudié cette méthodologie, nous l’avons étendu à d’autres propriétés notamment à des matériaux (scintillateurs) présentant des propriétés de détection et de discrimination des rayonnements neutrons/gamma en introduisant des chromophores au sein de nos composés. Le couplage de type Ullmann utilisé a également permis d’élaborer des composés pouvant présenter des propriétés électroniques (conduction et électrochromisme). / Ionic liquids based on imidazolium are an excellent platform that can be designed to promote liquid crystalline phases. In order to introduce additional properties, we synthesized compounds with a rigid expanded core. Herein, we reported an Ullmann-type coupling using only Cu(II)-NaY as catalyst and potassium carbonate as base. This synthetic approach avoids the use of solvents, inert atmosphere and ligands. We have optimized this coupling using the technique of microwave synthesis (reduction of reaction time and by-products formed). After studying this methodology, we have extended it to other behaviors. Thus we have synthesized ionic materials (scintillators) with properties of detection and discrimination of radiation neutrons/gamma by introducing chromophores in our compounds. This Ullmann-type coupling has allowed to prepare compounds that can have electronic properties (conduction and electrochromism).

Engineering 2D organic nanoarchitectures on Au(111) by self-assembly and on-surface reactions / Elaboration de nanoarchitectures organiques bidimensionnelles par auto-assemblage et réactions sur surfacePeyrot, David 06 January 2017 (has links)
Ces dernières années ont été marquées par de grandes évolutions technologiques à travers notamment une course à la miniaturisation. De gros efforts de recherche se concentrent en particulier sur le domaine de l’électronique organique mais aussi sur de nouveaux matériaux bidimensionnels comme le graphène. Ces matériaux 2D présentent des propriétés physiques exceptionnelles et sont des candidats prometteurs pour le développement de futurs dispositifs électroniques. Au cours de cette thèse, l’approche ascendante, qui consiste à assembler ensemble des petites briques élémentaires, a été utilisée pour élaborer des nanostructures bidimensionnelles originales sur des surfaces. Des états électroniques localisés dus à un couplage électronique latéral particulier entre les molécules ont été observés. Quatre nanoarchitectures hybrides ioniques-organiques différentes ont été réalisées en faisant varier la température de la surface. Des nanostructures organiques covalentes ont aussi été élaborées par une réaction de couplage d’Ullmann sur la surface. Deux précurseurs différents en forme d’étoile avec des substituants iodés et bromés respectivement, ont été étudiés. De grandes nanostructures carbonées hexagonales poreuses ont notamment été synthétisées en faisant varier la température du substrat. Ces travaux ouvrent de nouvelles perspectives pour la réalisation de matériaux organiques bidimensionnels aux propriétés contrôlées. / Over the last few years, important technological developments were made following a trend towards miniaturization. In particular, lots of research efforts are put into the research on organic electronics and on 2D materials like graphene. Such 2D materials show great physical properties and are promising candidates for the development of future electronic devices.In this project, bottom-up approach consisting in assembling elementary building blocks together, was used to engineer novel twodimensional nanostructures on metal surfaces. The properties of these two-dimensional nanostructures were investigated using Scanning Tunneling Microscopy (STM) and X-ray Photoemission Spectroscopy (XPS). Two-dimensional nanostructures based on the self-assembly of organic building blocks stabilized by intermolecular interactions were engineered. In particular, nanostructures stabilized by hydrogen bonds, halogen bonds and ionic-organic interactions were investigated. Localized electronic states due to specific molecular lateral electronic coupling were observed. Four different ionic-organic nanoarchitectures were engineered varying the substrate temperature. Covalent organic nanostructures were also engineered by onsurface Ullmann coupling reaction. Two different star-shaped precursors with iodine and bromine substituents respectively, were investigated. Large periodic porous 2D covalent hexagonal carbon nanostructures weresuccessfully engineered by temperature driven hierarchal Ullmann coupling. These results open new perspectives for the development of 2D organic materials with controlled structures and properties.

Sintese van amino-arielaldehied verbindings / Marlene PrinslooPrinsloo, Marlene January 2015 (has links)
Die soeke na sterk hoë-verrigtingspolimere het gelei tot die idee om ʼn volledig
gekonjugeerde polimeer te ontwikkel vir moontlike gebruik in die motorindustrie. Hierdie
polimeer moet soortgelyke eienskappe as dié van Kevlar besit, aangesien die beoogde
polimeer vir die bakwerk van battery-aangedrewe voertuie gebruik sou kon word. Die
selfpolimerisasie van 4,6-diaminobenseen-1,3-dikarbaldehied is as die gewenste
gekonjugeerde polimeer beskou.
Tydens die studie is daar gefokus op die sintese van die monomeer 4,6-diaminobenseen-
1,3-dikarbaldehied. Die sintese van monomere wat beide funksionele groepe wat aan die
polimerisasie deelneem, op dieselfde molekuul besit, was uitdagend, omdat hierdie
monomere baie maklik selfpolimerisasie kan ondergaan. Hierdie studie het ook na groener
en korter sinteseroetes om 4,6-diaminobenseen-1,3-dikarbaldehied of derivate daarvan te
sintetiseer gekyk, aangesien die sintese van 4,6-diaminobenseen-1,3-dikarbaldehied in die
verlede met baie lang sinteseroetes en gevaarlike chemikalieë uitgevoer is.
Sintese van 1,5-dibromo-2,4-dimetielbenseen (1), 1,5-dibromo-2,4-bis(dibromometiel)-
benseen (2), 4,6-dibromobenseen-1,3-dikarbaldehied (3) en 1,3-bis([1,3]dioksolaan)-4,6-
dibromobenseen (5) is suksesvol uitgevoer, maar tydens die koper-gekataliseerde Ullmanntipe
reaksies om 4,6-diaminobenseen-1,3-dikarbaldehied (4) te sintetiseer, het slegs poeiers
gevorm wat nie oplosbaar in organiese oplosmiddels is nie. Om die selfpolimerisasie
moontlikhede van 4 uit te skakel is 5 gesintetiseer. ʼn Poging om 1,3-bis([1,3]dioksolaan)-
4,6-diaminobenseen (6a) vanaf 5 te sintetiseer het egter tot geen reaksie gelei nie.
Molekuulmodellering van die Ullmann-tipe reaksies om 6a en 4,6-dimetielbenseen-1,3-
diamien te sintetiseer is gedoen om die reaksie te ondersoek. Daar is gevind dat ʼn 1,3-
diketoonligand wat aan die koperkatalisator bind, nodig is om die reaksie te verbeter. Vanuit
die resultate van die studie is ook gevind dat ʼn Ullmann-tipe reaksie nie met 5 sal plaasvind
nie, aangesien dit energeties nie so voordelig is nie.
Spektroskopiese analise van die poeiers wat tydens die sintese van 4 gevorm het, bevestig
dat die poeiers polimere is. Dit blyk egter dat dit nie die voorgestelde rigiede polimeer is wat
gevorm het nie, maar dat dit eerder ʼn amorfe kinasolientipe produk is. / MSc (Chemistry), North-West University, Potchefstroom Campus, 2015
