外文摘要：A l-[2-methy]-5-(4-tetraphenylporphyrmphenyl)-3-thienyl)-2-[2-methyl-3-thienyl]cyclo- pentene combined by 3,3'-(l-cyclopentene-l,2-diyl)-bis(5-chloro-2-methyl)thiophene and tetraphenyl- porphyrin can transform between the open isomer and the closed isomer upon the irradiation of UV or visible light. Thus they can be utilized to write binary data. Furthermore, the open form can emit luminescence but the closed cannot while irradiated by another light that cannot cause optical chemical reactions. Therefore, data can be read out without damage.
