Four rigid-rod sensitizers, made of a phenylethynyl spacer substituted with a chromophore and two COOR binding groups, were prepared to study dynamics of electron injection at the interface of metal oxide semiconductor nanoparticles. Dimethyl Ru(bpy)2(5-(5-1,10-phenanthrolinyl)ethynyl)isophthalate) 2+ (4a), dimethyl Ru(bpy)2(5-(4-(2,2′-bipyridinyl)ethynyl)isophthalate) 2+ (4b), dimethyl 5-(1-pyrenylethynyl)isophthalate (4c), and dimethyl 5-(9-anthracenylethynyl)isophthalate (4d), were synthesized and characterized. Their absorption spectra, emission spectra, and electrochemical properties have been studied in acetonitrile and hexane solutions at room temperature.
