Design and synthesis of artificial receptors for selective and differential sensing

Zhang, Tianzhi, 1973- 29 August 2008 (has links)
This dissertation consists of four chapters. The first chapter provides an in-depth background of synthetic receptors for recognitions of phosphorylated molecules. This chapter covers synthetic receptors developed within the last two decades, and it focuses on the diverse functionalities and detection techniques involved in the receptor design. Chapter 2 discusses the synthesis and employment of a metalated receptor for the selective recognition of organic phosphates and phospho-amino acids, and describes a receptor with a pseudo tetrahedral cavity, which was found to be selective to phosphate, was synthesized utilizing a new and efficient synthetic route. UV-Vis titrations were used to determine binding constants for various organic phosphates and phospho-amino acids. The receptor:Cu(II) complex was found to differentiate the degree and size of phosphate substitutions. Chapter 3 describes the synthesis and application of a type of differential receptors for the recognition of phosphorylated tri-peptides from regular tri-peptides. The tri-peptide couples described in this chapter were part of sequences in protein Filamentous R-synuclein, which was discovered to have a close relation to Parkinson's disease. Extensive Ser129 phosphorylation was observed in diseased brains. Both solid phase and solution phase differential receptors were obtained in the investigations of peptide differentiation. A series of screening methods were applied to narrow down the system combinations. Linear discrimant analysis (LDA) statistical analysis generated a large spatial separation among six tripeptides. Chapter 4 describes the synthesis of a boronic acid based receptor for carboxy and phospho sugars recognition. Due to the large affinity to gluconic acid, which is the only product of enzyme catalyzed glucose oxidation, this receptor was successfully applied in determination of glucose concentration in human serum.

Calix[4]arene transition metal and crown ether based anion and ion-pair receptors

Evans, Andrew James January 2003 (has links)
The aim of this thesis is to develop novel receptors for the recognition of anions and ion-pairs. The guest binding and sensing properties of the receptors are studied by spectroscopic and electrochemical techniques. The ion-pair receptors described herein incorporate amide or urea functionalities for anion binding and crown ether moieties for alkali metal cation complexation. In addition, many receptors contain redox- and/or photo-active groups capable of sensing guest binding events. Chapter One introduces the field of supramolecular chemistry. A review of synthetic cation, anion and ion-pair receptors reported in the literature is undertaken, and the formation of selfassembled architectures is discussed. Chapter Two details the synthesis and study of a range of new upper-rim functionalised calix[4]arene anion and ion-pair receptors. The anion and ion-pair binding and sensing properties of the receptors are investigated by ¹H NMR spectroscopy, electrochemistry and luminescence spectroscopy. Two ion-pair receptors display a positive cooperative ion-pair effect, whereby the presence of potassium cations causes an enhancement in the strength of anion binding via electrostatic interactions and conformational effects. Chapter Three centres on ion-pair receptors incorporating an azacrown group for alkali metal cation complexation together with amide functionalities for anion binding. Receptors containing either ferrocene or transition metal dithiocarbamate groups are capable of electrochemically and/or optically sensing the binding of anionic guests. Chapter Four describes disulphide-appended receptors designed for self-assembly onto gold surfaces. A ferrocene- and disulphide-appended calix[4]arene receptor incorporating hydrogen bonding moieties forms self-assembled monolayers on gold electrodes which exhibit a surface sensing amplification in the electrochemical recognition of anions. In addition, the assembly of receptors onto gold nanoparticles is explored with the aim of producing UV-VIS spectroscopic sensors for guest binding. Chapter Five reports the experimental procedures and characterisation for all products. The Appendices provide information on experimental techniques, list the crystallographic data and summarise all the receptors studied.
