An intramolecular benzene excimer is demonstrated to form within DBP3; it exhibits strong redshifted emission with maximum at 540\u2013640\u00a0nm. \u201cIntrinsic\u201d fluorescence from DBP3 is dramatically quenched down to \u03c4 = 50\u2013400\u00a0fs in all the solvents studied. Fs-TA and time-resolved fluorescence spectra have proved that relaxed intramolecular benzene excimer is formed from S1 state via hot excimer state with three lifetime components: 50\u00a0fs, \u223c3.5\u00a0ps, and \u223c25\u00a0ps, which are of the inertial (electronic) and diffusive parts of the relaxation due to solute\u2013solvent interaction.
