Designs And Syntheses Of Organic Electroluminescent Materials Self-assembling By Non-covalent Bond

The self-assembly procedure based on the supramolecular chemistry is of great importance to the understanding and the simulation of both chemical and biochemical reaction procedures. In this thesis, the self-assembly organic functional materials are assorted, and their structures, properties, mechanism as well as the development are reviewed briefly. And their prospective applications are pointed out as well.In this paper, we designed a novel hydrogen-bond self-assembled "molecular duplex" with electroluminescent group according to hex-hydrogen-bond self-assembly supramolecular system, which is a novel, fluorescent organic functional material. It can be used to fabricate organic electroluminescence devices, and moreover by using this method, we can also combine hole and electron-transporting moieties groups to modify this self-assembly system, which may obtain a sorts of novel organic electroluminescent materials. The light-emitting group in the "molecular duplex" designed in this paper is 1, 8-naphthalimide, which could emit strong yellowish green fluorescence. Many other light groups can also be attached to this "molecular duplex" for more and wider prospective applications.This hydrogen-bond self-assembled "molecular duplex" is divided into three segments for syntheses, and more than twenty intermediates were synthesized, and their molecular structures were characterized by MS, IR and 1HNMR., and their photoluminescence properties were studies as well.
