| Abstract: | Photophysical constants of three novel ruthenium dyes derived from tridentate pyridinediimine (pydim) ligands has been declared
and their photoluminescent properties were investigated in solvents of dichloromethane (DCM), tetrahydrofuran (THF) and ethanol
(EtOH) by UV-Visible absorption, emission and excitation spectra. The quantum yield, fluorescence decay time, molar extinction
coefficient and Stoke’s shift values of the novel ruthenium complexes were determined. The perfluoro compound (PFC) nonadecafluorodecanoic
acid which is also known as medical gas carrier has been used for the first time together with newly synthesized Ruthenium
complexes in ethyl alcohol. The utilities of oxygen sensing materials were investigated in EtOH in presence of chemically
and biochemically inert PFC. |
