中文摘要	five novel organic conjugated derivatives containing multifraction twisted acene units have been synthesized and characterized. these compounds and the model molecule 2-methyl-5,12-diphenyl-6:7,10:11-bisbenzotetracene emit strong blue light in diluted solution with quantum yields of 0.21-0.67, while in the solid state, except for the 1,2,3,4,5,6-hexa(2-(5,12-diphenyl-6:7,10:11-bis-(4'-tert-butylbenzo)tetracene))benzene, green luminance is seen. the experimental results also indicate that the multifraction structure leads to a significant fluorescence enhancement (over two times) compared to the monomer, which might be attributed to the formation of delocalized excited state in multibranch structures. the quantum-chemical calculation implies that only two branches are involved in formation of the delocalized system for the multibranched derivatives. furthermore, the organic light-emitting diode (oled) devices using compounds 1,4-di(2-(5,12-diphenyl-6:7,10:11-bis(4'-tert-butylbenzo)tetracene))benzene, 1,3-di (2-(5,12-diphenyl-6 :7,10:11-bis(4'-tert-butylbenzo)tetracene))benzene, and 1,3,5-tri(2-(5,12-diphenyl-6:7,10:11-bis(4'-tert-butylbenzo)tetracene))benzene as emitters exhibit good electroluminescent performance. our systematic studies might provide more chances to challenge the rational design and synthesis of new- and high-generation branched dendrimers.
