Abstract: N-phenyl-2,3-bis- [3-(1-ethyl-2-methyl-indoyl)]-maleimide (Compound I)was synthesized and its structure was characterized. Photochromic Property of compound I was examined by steady state and laser flash photolysis techniques. The resuhs indicate that, withthe excitation of 248nm laser pulse, I shows photochromisrn in acetonitrile, and the transientabsorption of the photopreduct was observed (λmax= 610nm), but in steady state experiment, no photochromic product of I can be detected after irradiation with either 366nm or450nm light. The reason is probably that the photopreduct is unstable, in other words, itslifetime is too short to be detected with steady state method.

Key words: synthesis, maleimide, photochromism, transient absorption spectra
