Preparation and optical properties of benzo[1,2-b:4,5-b']dithiophene derivatives
摘要
Abstract
Compounds 4,4'-(4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene-2,6-diyl)bis(2,3,5,6-tetrafluorobenzonitrile)(TBDBT)and 4,4'-(4,8-bis((2-ethylhexyl)oxy)benzo[1,2-b:4,5-b']dithiophene-2,6-diyl)bis(2,3,5,6-tetrafluoroben-zonitrile)(OBDBT)containing conjugated benzo[1,2-b:4,5-b']dithiophene were designed and synthesized by the classical Stille coupling reaction.Theoretical calculations show that the conjugation of compound OBDBT increases when 2-ethylhexyloxy is introduced to the benzo[1,2-b:4,5-b']di-thiophene skeleton,which emits strong red light,and the fluorescence quantum yield reaches 81%.Therefore,substituents can be used to adjust the conjugation of benzo[1,2-b:4,5-b']dithiophene derivatives to achieve the preparation of red-light materials with high fluorescence quantum yield.关键词
