Transient Absorption Properties of 1, 8, 15, 22-Tetra-N-Pentyloxy Metallophthalocyanines and Metal Free Phthalocyanine

Abstract:

In this paper, the triplet properties of a series of 1, 8, 15, 22-tetra-n-pentyloxy metallophthalocyanines [α-MPc(OC₅H₁₁)₄), M=Fe, Ni, Cu, Zn] and metal free phthalocyanine [H₂Pc((OC₅H11)4)] were investigated using flash photolysis technique in solutions at the concentration of 10-5mol/L. The triplet absorption curves and triplet lifetimes were acquired. ZnPc(OC₅H₁₁)₄ exhibits a strong triplet absorption and has long triplet lifetime due to the d-electron and charge transfer effect.
