Abstract Thin solid films of free base meso-tetra-arylporphins and their zinc, copper, platinum and palladium complexes have been exposed to highlevels of dinitrogentetroxide (NOX). The optical spectra (300–850 nm) were recorded in transmission before and after exposure to NOX. On the basis of the foregoing spectroscopic evidence, films resistant to permanent chemical damage by highlevels of NOX (>

(platinum and palladium) inserted meso-functionalized porphyrins have been newly synthesized and characterized by single-crystal X-raydiffraction, spectroscopic, electrochemical, and photochemical techniques. Structure-function relations in terms of platinum and palladium heavy metal ions in the porphyrin cavity and meso-aromatic substituents on porphyrin ring periphery in governing singlet oxygen quantum
