染料敏化太阳能电池光敏剂卟啉儿茶酚的密度泛函和含时密度泛函研究
DFT and TD-DFT study on the sensitizer for dye sensitized solar cell:porphyrin catechol
摘要
Abstract
The geometry,electronic structure,IR and Raman frequencies of dye sensitizer 5,10,15-trisphenyl-20-(3,4-dihydroxybenzene)porphyrin(porphyrin catechol,TPP-cat)were studied by using density functional theory(DFT)with hybrid functional B3LYP.The charge populations and bonds properties were analyzed via natural bond orbital(NBO)method.The strongest IR absorption and Raman activity located at 1175.81 cm-1and 1587.18 cm-1respectively.The electronic absorption spectra of TPP-cat in water were investigated by using TD-DFT calculations.The Soret band and Q-bands are all assigned to π→π* transition.and the transition at 354 cm-1 is related to photoinduced intramolecular change transfer process.关键词
