| 英文摘要 | The Solution photophysical properties of two conjugated dithienothiopliene (DTT)-perylene bisimide (PBI) systems-a polymer, poly {[N,N'-bis(2-decyl-tetradecyl)-3,4,9,10-perylene diimide-1,7-diyl]-alt-(dithieno[3,2-b:2',3'-dithiophene-2,6-diyl)}, and a small molecule, 1,7-bis(dithieno[3,2-b:2',3'-d]thiophene-2-yl)-N,N'-bis(2-decyl-tetradecyl)-3,4,9,10-perylene diimide-in Solution have been investigated. Strong quenching of the fluorescence of the PBI moiety was observed in both DTT-PBI systems, suggesting the possibility of an efficient intramolecular electron-transfer process. The kinetics of photoinduced electron transfer in the DTT-PBI polymer and monomer in solutions were explored by femtosecond time-resolved transient absorption spectra. It was found that both the rates of charge separation and charge recombination in the DTT-PBI polymer were approximately double those in the small molecule. This indicates that electronic Coupling plays an important role in the electron-transfer process in a polymer system. |
