英文摘要: This project will concentrate on the design and synthesis of new conjugated molecules containing framework exhibiting aggregation-induced emission behaviors. The incorporation of new conjuagted moieties (im particular with thiophene moiety) to the AIE framework aims to increase the intermoelcuar pi-pi interactions which will increase carrier mobility and simultaneously keep AIE property. The self-assembly nanostructures and organized thin films of these new conjugated molecules will be prepared and their light-emission and carrier mobility properties will be investiagted. Also, the correlations between the optoelectronic properties and the molecular and self-assembly structures will be explored. The target of this project is to generate new molecular materials with both high light emission efficiency and carrier mobility. Such molecular materials are expected to be useful in various optoelectronic devices.
