Spectral properties of intramolecular charge transfer fluorescence probe 1-keto-2-(p-dimethylaminobenzal)-tetrahydronaphthalene.
The photophysical properties of a new compound 1-keto-2-(p-dimethylaminobenzal)-tetrahydronaphthalene in various solvents at room temperature were characterized by the absorption and steady-state fluorescence technique. The bathochromic shift on the emission spectra, the broad halfwidth of the fluorescence band and the increase in the excited state dipole moment occurred. These results gave the evidence about the intramolecular charge transfer (ICT) character in the emitting singlet state of the compound.
