| Abstract: | Two new ruthenium bipyridine photosensitive dyes with different ligands were synthesized from substituted 2,2'-bipyridine.The structures of the dyes and their intermediates were characterized by IR and 1HNMR.The photophysical and electrochemical properties of the dyes were studied,and the results were satisfactory:the maximum absorption wavelengths in the visible region of them were 521 nm and 545 nm,and the calculated values of the band gaps were 1.87 eV and1.58 eV.The photoelectric conversion efficiencies of the dyes based DSSCs were10.21% and 9.97%. |
