Abstract
The complex Pt(II) (hematoporphyrinH(2))Cl-2 which contains free base porphyrin as a bidentate ligand is light sensitive. In DMF a photosubs titution takes place. The porphyrin is released with phi similar to 2 X 10(-3) at lambda(irr) = 405 nm. It is assumed that the photolysis or iginates from a ligand field state which is populated from pi pi intr aligand states. In a secondary photolysis the porphyrin undergoes a de composition in agreement with previous results.
