Photophysical properties of palladium/platinum tetrasulfonyl phthalocyanines and their application in triplet–triplet annihilation upconversion

Abstract

Pd/Pt tetrahexylsulfonyl-substituted phthalocyanine complexes were synthesized and showed a high triplet state energy level, a long-lived triplet state and triplet–triplet-annihilation upconversion properties.
