A series of pyrryl substituted fulgides have been designed and synthesized. Photochromic properties of fulgides have been investigated in various organic solvents. Photochromic mechanism of this kind of fulgides have been studied by means of nanosecond laser flash photolysis technique, both of excited singlet and excited triplet state are involved in the photocyclization process. A sample of optical disk was prepared by spin coating method. Photoinduced electron transfer between pyrryl fulgide and TCNQ has been found and studied by UV-Vis and EPR spectroscopic techniques.

The pale yellow (E)-isopropylidene-succinic anhydride 3b undergoes a reversible photochemical reaction to give the deep blue 7,7a-dihydro-1,2,4,7,7,7a-hexamethylindole-5,6-dicarboxylic anhydride 4b which is thermall
