36. In benzonitrile, the emission maximum of G1 was shifted to 660 nm, suggesting the highly polar nature of the emissive state.
37. 2 or benzonitrile solution of G1 did not exhibit clear transient absorptions. These results suggest that the intermediate observed in these measurements is not an ICT state but a triplet state. A pathway from the Franck-Condon state of G1 to the triplet state is not elucidated yet, but the ICT state is assumed to be formed as a primary intermediate that gives the fluorescence and is transformed into the triplet state to some extent.
