Synthesis and Characterization of a Series of Bis-homoleptic Cycloruthenates with Terdentate Ligands as a Family of Panchromatic Dyes.

摘要: A series of six homoleptic bis-cyclometalated ruthenium complexes, Ru(N^N^C)2, is reported where N^N^C a 6-(2,4-difluoro-3-R3-phenyl)-4-R2-4′-R1-2,2′-bipyridine with R3 = −H or −CF3 and R2 R1 −COOEt −CF3. An effective synthesis the ligands complexes described. The UV–visible absorption studies demonstrate that these are panchromatic dyes absorbing up to 900 nm. Importantly, onset depends only on substitution metalated phenyl, whereas intensity throughout spectra function substituents both phenyl bipyridine moieties. same trend observed in electrochemistry as redox gap oxidation reduction potentials Preliminary tests sensitizer for dye-sensitized solar cells number anchoring groups dye has major influe...
