There is a growing interest to mimic major processes in natural photosynthesis via artificial systems in order to harvest solar energy. In the present study, we wish to report newly synthesized molecular triads comprised of Zinc porphyrin-boron dipyrrin-triphenylamine entities.Further, supramolecular tetrad is formed by axial ligation of imidazole functionalized fullerene. Systematic spectral, electrochemical and emission studies are performed to probe sequential energy transfer followed by electron transfer events in the newly synthesized triads. Computational studies using B3LYP/3-21G* are performed to arrive at the geometry and electronic structures. Photochemical study using time-resolved emission is performed to probe electron transfer events. Further, organic photocells are being built to directly convert light energy into electricity.
