碩士 === 淡江大學 === 化學學系碩士班 === 93 === 3,4-diaryl-substituted maleimide derivatives with π conjugated substituents were designed and synthesized and compared with theoretical computational . These maleimide derivatives were found to exhibit large Stokes shift due to a change of the geometric structure from the ground state (S0) to the first excited state (S1). Calculations were carried out using MOPAC97/ AM1 semiempirical computational methods were used to generate the ground and excited states structure of maleimide-based withπconjugated substituents. After geometry optimization, the absorption and emission energies of these derivatives were estimated by the semiempirical ZINDO methods.
