Optoelectronic Properties of Discotic Materials for Device Applications

A parameter of prime importance in determining the successful technological application of organic compounds as the active layers in the rapidly advancing area of molecular (opto)electronics is the mobility of charge within these materials. This parameter controls for example the switching speed of field effect transistors, the intensity of light-emitting diodes, and the collection of the photo generated charges in photovoltaic cells. Contents include: Discotic liquid crystals for molecular electronics, Experimental techniques, the Mobility and decay kinetics of charge carriers in discotic hexabenzocoronenes, the Optical and charge transport properties of discotic materials with large aromatic hydrocarbon cores, pi-deficient discotic mesogens for electron transport, Tailoring discotic mesophases: columnar order enforced with hydrogen bonds, Aniotropy in the mobility and photogeneration of charge carriers in thin films of discotic hexabenzocoronenes, columnarly self-assembled on friction-deposited PTFE, Thermal switching of the optical anisotropy of a macroscopically aligned film of a discotic liquid crystal, Aligned thin films of discotic hexabenzocoronenes: anisotropy in the optical and charge transport properties, Photo-induced charge separation in a blend of perylenediimide and hexabenzocoronenes derivatives studied by FP-TRMC.Piris, Jorge is the author of 'Optoelectronic Properties of Discotic Materials for Device Applications ', published 2004 under ISBN 9789040725203 and ISBN 9040725209.
