The photophysics of these dyes has been measured and were related to the substituents on triphenylamine group and anchoring groups. The most red-shift was showed in the case of the dye MOTTC containing methoxy substituents as electron-donating group and cyanoacrylic acid as electron-withdrawing group. MOTTC and its derivatives can absorb the visible light and is suitable for the application of solar cell
