Up-Conversion Luminescence of a High Soluble Zinc Phthalocyanine--Epoxy Derivative

Synthesis and photoelectric properties of a high soluble zinc phthalocyanine--epoxy derivative are investigated. The derivative can be solubilized in convenient solvents, such as CH₃OH, CH₃CH₂OH and H₂O. The fluorescence and UV-visible analyses indicate that the ZnPc--epoxy derivative still maintains the plane structure which comes from Zn(4,4^',4^'',4^''' -ta)Pc and the derivative has obvious up-conversion luminescence in room temperature. The up-conversion luminescence can be explained by the selection rule depending on the two-photon absorption.
