Spectroscopic Properties of a Novel Zinc Phthalocyanine with four 17-Membered Crown Ether Voids

摘要

A zinc phthalocyanine containing (17-crown-5) ether subunits has been synthesized.UV-visible absorption and fluorescence emission spectra and associated photophysical parameters have been determined. In addition to the fluorescence at 710 nm from S1. a strong upper excited state emission around 424 nm has been detected. X-ray structural analysis showed that the crown ether unit is conformationally deformed and oblate like that accounted for the unusual spectroscopic
