Two-photon induced photorelease of nitric oxide from ruthenium-nitrososyl complexes containing ligands with various push-pull capabilities

Abstract : The work "Two-photon induced photorelease of nitric oxide from ruthenium-nitrosyl complexes containing ligands of various push-pull capabilities" was devoted to the revealing of main factors that determine the efficiency of ruthenium-nitrosyl complexes in two-photon absorption (TPA) and the improvement of TPA cross-section through modification of the ligands nature and their structure. Starting from complexes previously obtained by the research group of Prof. I. Malfant, we have modified their structure in several directions. It was shown that substitution of monodentate ligands by 2,2'-bipyridine in ruthenium complexes with nitrosyl ligands leads to a slight increase of their TPA cross- section, however this modification decreases the quantum yield of the nitric oxide photo release. Synthetic part of the work was mainly aimed at the modification of the ligand.
