英文摘要	by choosing a simple triphenylamine electron donor, we herein compare the influence of electron acceptors benzothiadiazole benzoic acid (btba) and cyanoacrylic acid (ca), on energy levels, light absorption, and dynamics of excited-state evolution and electron injection. dft and time-dependent dft calculations disclosed remarkable intramolecular conformational changes for the excited states of these two donor-acceptor dyes. photoinduced dihedral angle variation occurs to the tri-phenylamine unit in the ca dye and backbone planarization happens to conjugated aromatic blocks in the btba dye. femtosecond spectroscopic measurements suggested the crucial role of having a long excited-state lifetime in maintaining a high electron-injection yield because a reduced driving force for a low energy-gap dye can result in slower electron-injection dynamics.
