Charge Transfer Dynamics

Solvent sensitive excited state dynamics of DNBP is explored. In polar solvents, the ultrafast barrierless TICT process is the major relaxation pathway, whereas, in nonpolar solvents the excited state undergoes the PICT process, followed by efficient intersystem crossing to the triplet state.

Intramolecular Charge Transfer

Intramolecular charge-transfer increases the requirement on wavefunction-based methods to evaluate γ of trimethylenemethane derivatives whereas DFT/M06-2X performs equally well.
