Absorption spectra were measured in EtOH solution. bTransmittance spectra were measured on 1-layer TiO2 film. cRedox potential of dyes on TiO2 was measured in CH3CN with 0.1 M (-C4H9)4NPF6 as a scan rate of 100 mV s−1 (vs. NHE). d values were estimated from the onset of absorption spectrum. e was calculated by . fPerformances of DSSCs were measured with 0.18 cm2 working area. Electrolyte: 0.6 M DMPImI, 0.05 M I2, 0.5 M TBP, and 0.1 M LiI in acetonitrile. gEnergy level calculated by experiment. hEnergy level calculated at the B3LYP/3-21 G.
