| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 99 === In this thesis, we have synthesized a serious of novel organic dyes base on diphenylamine. The main strategy is D-π-A structure, the diphenylamine for electron donor, phenyl and conjugated moiety for electron bridge, with cyanoacetic acid for acceptor. Besides, to confirm the retarding of charge combination from electrolyte, the alkyl-functionalized groups were joined like norbornane、cyclohexane in modified group for the function of steric hindrance.
All of these compounds were characterized by UV/VIS spectrophotometer, fluorescence spectrophotometer and cyclic voltammetry. Also be applied in dye-sensitized solar cell components, and the power-conversion efficiency was measured by the AM1.5 simulated solar light system.
