资源简介：
Five cationic platinum(II) complexes
bearing a 2-(3′-substituted aryl)pyridine cyclometalating ligand
(C∧N) and a neutral Ar-BIAN ligand have been synthesized:
[Pt(ppy)(PhBIAN)]PF6 (1), [Pt(3Fppy)(PhBIAN)]PF6 (2), [Pt(3MeOppy)(PhBIAN)]PF6 (3), [Pt(3MeOppy)(4-FPhBIAN)]PF6 (4), [Pt(ppy)(4-MeOPhBIAN)]PF6 (5). All complexes
have been characterized by NMR spectroscopy and mass spectrometry.
Complexes 2 and 3 have been characterized
by X-ray crystallography. Structure–property relationships
were established from UV–visible spectroscopy and cyclic voltammetry
studies. Interestingly, we found that when both the C∧N and the Aryl-BIAN ligands contained electron-donating MeO groups
the absorption spectrum for the platinum complex extended out to 650
nm. The electrochemical studies of these complexes established that
they are electronically compatible dye molecules for dye-sensitized
solar cells.
