Abstract
Spectral-luminesnce, nonlinear-optical and photochemical characteristics of metal complexes with new tetraphenylporphyrin (TPP) derivatives, with atom Lu(III) or Gd(III) in the ligand-complexone or as a central ion, in liquid and frozen solutions and in state-solid polymer matrices also are studied. The limiting coefficient (LC=T0/TW) at power density about 250 MW/cm2 chosen as gauge of nonlinear-optical properties. Phototransformation quantum yield under 2nd harmonic of Nd-YAG-laser irradiation (φ532) chosen as gauge of photostability. Results of investigation show significant nonlinearity of studied substances caused by reverse saturable absorption. Compounds photostability quite enough, spectral characteristics of irradiated samples are evidence of protonated nature of photoproduct, which in one's part make contribution to power radiation absorption.
