英文摘要
A novel class of liquid crystalline discotic material which is able to form super-molecular self-assembly with combined conduction of electronic and ionic carriers was designed and prepared for the first time. Other new materials prepared also included disk-rod liquid crystalline materials, dendritic polymers with discotic unit, and many other optically active discotic were prepared. Phase transitions from/to liquid crystalline were investigated. . Homeotropic molecular alignment on single substrate geometry was successfully achieved. It became one of few examples in this field internationally. A possible mechanism for the control of such alignment was proposed. Also prepared was nano-fiber using porous template from a discotic polymer composite.. Optoelectronic properties were investigated and devices were prepared. Chrage carrier mobility of these discotic were measured and calculated theoretically. Devices using discotic materials as functional layers were prepared. Novel hybrid PV device were invested with improved response; an impressive color stable blue organic light emitting device at a wide range driving voltages also was achieved.
