| 内容記述 | Emission, excitation, and absorption spectra of diphenyltetradecaheptaene (DP7) have been measured in solvents with different polarizabilities, together with the Raman spectrum at room temperature. DP7 exhibits dual fluorescence from the 2 1Ag(S1) and 1 1Bu(S2) states in room temperature solution. It is shown that the 2 1Ag/1 1Bu fluorescence intensity-ratio varies significantly depending on the solvent polarizability. This observation was interpreted on the basis of the coupling strength between the 2 1Ag/1 1Bu states which is determined mainly by the 2 1Ag–1 1Bu energy separation. Fitting of the spectra with sum of Gaussians reveals a significant difference in Franck–Condon envelop between the 2 1Ag and 1 1Bu fluorescence spectra, which is originating from the large difference in the C–C and C[Double Bond]C stretching mode displacements between the 2 1Ag and 1 1Bu states. | |||||||
