The photochemical behavior of [Ru(NO)(NO)2pc] (pc = phthalocyanine) is reported in this paper. In addition to ligand localized absorption bands (λ < 300 nm), the electronic spectrum of this complex in dichloromethane solution was dominated by an intense absorption at 640 nm characterized as Q-bands. Irradiation of [Ru(NO)(NO)2pc] at 366 and 660 nm led to the production of nitric oxide (NO) as detected by a NO-sensor. NO production by light irradiation at high energy involved excitation of dπ–π∗dπ–π∗ transition, while a photoinduced electron transfer occurred at long wavelength irradiation. The NO quantum yields varied from 1.4 × 10−3 to 2.3 × 10−2 mol einstein−1, depending on oxygen concentration.
The photolysis of [Ru(NO)(NO)2pc] (pc = phthalocyanine) at 366 and 660 nm releases NO with quantum yield depending on oxygen concentration. A range from 1.4 × 10−3 to 2.3 × 10−2 mol einstein−1 was observed and the photochemical pathway is depending on wavelength light irradiation.Figure optionsDownload as PowerPoint slide
