NIR-emissive iridium(iii) corrole complexes as efficient singlet oxygen sensitizers. Issue 40 (23rd September 2015) - Sinha, Woormileela
Abstract : The observed phosphorescence of the studied Ir(iii )corroles at ambient temperature appears at much longer wavelengths than the previously reported Ir(iii ) porphyrin/corrole derivatives. Efficiencies of these compounds in the generation of singlet oxygen are also studied for the first time. Abstract : Three new iridium(iii ) corrole complexes, having symmetrically and asymmetrically substituted corrole frameworks and judiciously varied axial ligands are prepared and characterized by various spectroscopic techniques including the X-ray structures of two of them. The observed phosphorescence at ambient temperature appears at much longer wavelengths than the previously reported Ir(iii ) porphyrin/corrole derivatives. Efficiencies of these compounds in the generation of singlet oxygen are also studied for the first time.
