摘要：

Time-resolved emission spectroscopy of "push-pull" stilbene derivatives has revealed the presence of an anomalous emission band appearing in the 5200-5600 angstrom spectral range. This anomalous band appears only in derivatives where the donor group is able to twist and depends on the solvent polarity, concentration and intensity excitation. This band, correlated to the presence of excited TICT states, is attributed to the emission of a "bicimer" species formed by the association of a pair of electronically excited states with large dipole moments.
