Abstract :
The aim of this study is the investigation of the optical limiting behavior of some azaporphyrins and related RSA mechanism, since all mechanisms have additive character. The optical limiting by RSA mechanisms depends on the structure of the coordination center in azaporphyrin complexes, solvent, initial transparency, energy of photon and intensity of radiation. Complexes octaphenyltetraazaporphyrine with the group III metals bearing halides as axial ligands, were chosen as objects in this study
