Abstract: Bismaleimides bearing electron-donating chromophore moieties, A(=)-D(*)-A(=) type monomers, i.e. N,N-bis(4-maleimidophenyl)methylamine (BMIPMA), N,N-bis(4-maleimidophenyl)aniline(BMIPA) and 2,5-bis(4-maleimido phenyl)-1,3,4-oxadiazole(BMIPODA) as well as their corresponding saturated model compounds, i.e. N,N-bis(4-succinimidophenyl)methylamine( BSIPMA), N,N-bis(4-succinimidophenyl)aniline(BSIPA) and 2,5-bis(4-succimidophenyl)-1,3,4-oxadiazole (BSIPODA) were synthesized. It was found that the fluorescence quantum yields of A(=)-D(*)-A(=) monomers were always dramatically lower than those of their corresponding saturated model compounds. These A(=)-D(*)-A(=) bismaleimides possess a strong SSQE, which is attributed to an intramolecular charge transfer interaction.

Key words: Fluorescence, Structural self-quenching effect(SSQE), Bismaleimides, Charge transfer complex
