Intramolecular charge transfer in conjugated donor-acceptor molecules may be accompanied by internal rotation leading to TICT (twisted intramolecular charge transfer) states. A dual fluorescence may be observed as in PCT-5 (Letard et al., 1994) (which resembles the well-known DMABN (see section 3.4.4) containing a dimethylamino group instead of the monoaza-15-crown-5) the short-wavelength...

The first example of e.t. controlled by solvent relaxation was probably the TICT state formation in DMABN and similar molecules [74]. The twisted intramolecular charge transfer state is, however, formed gradually the charge separation increases with the twist angle of the dimethylamino substituent...
