Consequently, this investigation centres around the kinetic and thermodynamic parameters involved in the solvent polarity dependent intramolecular photo-induced electron transfer processes in the dyad, indispensable for artificial photosynthetic systems. A quasi-reversible electron transfer pathway was elucidated with electrode-specific heterogeneous electron transfer rate constants. Graphical Abstract Solvent polarity controlled kinetic and thermodynamic parameters associated with intra-molecular photo-induced electron transfer processes in an electronically push-pull type dimethylaminoazobenzene-fullerene C60 donor-bridge-acceptor dyad are reported. A quasi-reversible electron transfer pathway is elucidated with electrode-specific heterogeneous electron transfer rate constants for the trans-dyad across the electrode/electrolyte interface.
