Aluminum Complexes of 2-Methyl-8-hydroxyquinolineFowler, David J. 08 1900 (has links)
The complex between Al(III) and 2-methyloxine has been prepared from various aqueous and aqueous-acetone solutions, both in the presence and the absence of acetate ion as an auxilliary complexing agent. The effect of pH on precipitation of the complex from 20% v/v acetone-water medium has been determined. Solid-phase hydrous aluminum oxide has been converted to the tris complex by the addition of a dioxane solution of 2-methyloxine. Infrared spectral evidence has been found for some degree of complexation from reactions in the melt between Al(III) and 2-n-propyl-, 2-n-butyl-, and 2-phenyloxine. / Thesis / Master of Science (MSc)

New Chelating Agents based on 8-HydroxyquinolineBillo, Edward Joseph 06 1900 (has links)
Several new potentially terdentate chelating agents based on the 8-hydroxyquinoline structure have been synthesized and characterized. Protonation constants of these ligands and formation constants of their chelates with selected metal-ions have been determined. Where possible, the chelates have been characterized by elemental analysis and other means.
The results show that the ligand 2-(2'-thienyl)-8-hydroxyquinoline acts as a sterically hindering bidentate donor; the unusual relationship found between the formation constants of its bis-chelates (K1 < K2) has been explained on the basis of steric effects.
The results of studies involving 4-amino-5-hydroxy-acridine and 4,5-dihydroxyacridine indicate that these ligands act as terdentate and bidentate donors, respectively. The failure of 4,5-dihydroxyacridine to act as a terdentate donor is explained in terms of chelate-ring strain. / Thesis / Doctor of Philosophy (PhD)

Development of 8-Hydroxyquinoline Metal Based Organic Light-emitting DiodesFeng, Xiaodong 31 July 2008 (has links)
Because of its potential application for flat panel displays, solid-state lighting and 1.5 µm emitter for fiber optical communications, organic light-emitting diodes (OLEDs) have been intensively researched. One of the major problems with current OLED technology relates to inefficient electron injection at the cathode interface, which causes high driving voltage and poor device stability. Making a low resistance cathode contact for electron injection is critical to device performance. This work mainly focuses on cathode interface design and engineering.
The Ohmic contact using a structure of C60/LiF/Al has been developed in electron only devices. It is found that application of the C60/LiF/Al contact to Alq based OLEDs leads to a dramatic reduction in driving voltages, a significant improvement in power efficiency, and a much slower aging process.
A new cathode structure based on metal-organic-metal (MOM) tri-layer films has been developed. It is found that MOM cathodes reduce reflection by deconstructive optical interference from two metal films. The absolute reflectance from the MOM tri-layer films can be reduced to as low as 7% in the visible light spectrum. In actual working devices, the reflectance can be reduced from ~80% to ~ 20%. MOM cathodes provide a potential low-cost solution for high contrast full-color OLED displays.
Low voltage Erq based OLEDs at 1.5 µm emission have been developed. The Erq/Ag cathode interface has been found to be efficient for electron injection. Dramatic improvement in driving voltage and power efficiency has been realized by implementing Bphen and C60 into Erq devices as an electron transport layer. Integration of Erq devices on Si wafers has also been demonstrated.
