<P>Photoinduced twisted intramolecular charge transfer (TICT) of <I>meso</I>-(4-dimethylamino)phenylamino subporphyrin <B>2</B> and <I>meso</I>-(4-nitro)phenylamino subporphyrin <B>3</B> has been r...
<P>Photoinduced twisted intramolecular charge transfer (TICT) of <I>meso</I>-(4-dimethylamino)phenylamino subporphyrin <B>2</B> and <I>meso</I>-(4-nitro)phenylamino subporphyrin <B>3</B> has been revealed by steady-state and time-resolved absorption/fluorescence experiments and quantum calculations. Subporphyrins <B>2</B> and <B>3</B> undergo molecular twisting at the C<SUB><I>meso</I></SUB>–N bond and the N–C<SUB><I>ipso</I></SUB> bond, respectively, to trigger intramolecular charge separation, which is restricted at low temperature or in viscous paraffin oil with concurrent fluorescence recovery of local excited states.</P>
