摘要：A new series of bisindolylmaleimide (BIM) derivatives were synthesized. The absorption and fluorescence properties of these compounds were investigated in solution and solid state. Dramatic difference in solid-state fluorescence emission spectra was observed by changing the substiments on the fluorophores skeleton from methyl to benzyl. We performed X-ray crystallographic analyses to elucidate the effect of the substituents of the non-conjugated linkage on the solid-state fluorescence emission spectra. The relationships between the solid-state photophysical properties and the chemical and crystal structures of 2,3-bis(N-benzyl-2'methyl-3'-indolyl)-N-methylmaleimide (1S) and 2,3-bis(N-benzyl-2'methyl-3'-indolyl)N-benzylmaleimide (5S) are discussed on the basis of the X-ray crystal data. Bis[2,3-bis(N-ethyl-2'methyl-3'-indolyl)-N-(prop-2-ynyl)maleimide] (1B) and 1S were utilized in non-doping host red EL device. The brightness reaches 393 cd m(-2) at 100 mA cm(-2) for 1S.
