The first year, the new electron-donating triphenylamine-containing boronic acid、monoamino、diboronic acid compounds and perylene-diimide having different donor substituted in the perylene moiety will be prepared. Second year of the proposal is to design and synthesize aromatic poly(amine-imide) with bulky or donor substituted in the side or main chain, polytriphenylamine, and other triphenylamine-containing donor-acceptor copolymer, respectively. The last year of the proposal is to prepare and characterize a series of 1,7-dibromo-perylene-diimide with triphenylamine substituents in the imide ring, then, these dibromo compound further react with triphenylamine-containing distannane or dibronic acid to obtain high Tg and thermostable donor-acceptor type π- conjugated aromatic polymer with perylene bisimide architecture. In addition, by varying the structure of conjugated aromatic unit, we will study the effect on UV-vis absorption, photoluminescent and electrochemical properties by UV-vis, fluorescence spectroscopy and cyclic voltammetry (CV). From these preliminary studies, the energy band gap, HOMO and LUMO values, and feasibility as photovoltaic materials will also be investigated.三苯胺駢苯衍生物共軛高分子太陽能電池二硼酸低能帶材料。triphenylamineperylene derivativesdonor-acceptor typeconjugated polymersdiboronic acidphotovoltaic materials.
