Photochemistry of Coordination Complexes: The Phthalocyanines

摘要

It is possible to relate the thermal and photochemical reactivity of the phthalocyanines to the existance of empty and filled pi -orbitals at energies which allow the oxidation and reduction of the macrocycle at moderate potentials. In this context, the photochemical reactivity of the phthalocyanines will be discussed in terms of the population of reactive charge transfer and n pi * (ligand centered) states and electron transfer reactions induced in the quenching of the low lying pi pi * (ligand centered) states. 3 figures.
