摘      要：Three 1-long gydrocarbon chain substituted pyrryl fulgides, (2, 4-dimethyl-1-hexadecy1-5-pheny1-3-pyrryl)- ethylidene (isopropylidene)succinic angydride (1E),(2, 4-dimethyl-1-octadecyl-5-phenyl-3-pyrryl)-ethylidene (isopropylidene) succinic anhydride (2E) and (2-methyl-1-(p-octadecoxyphenyl)-5-phenyl-3-pyrryl)- ethylidene (isopropylidene) succinic anhydride (3E) were synthesized. Their photochromic behaviors were also investigated. Compound 3E was obtained in much higher yield (41.7%) than others with an improved procedure.
