TL;DR: In this article, the dependence of photoinduced electron transfer reaction rates on the molecular structures of the donor and acceptor entities results in improving the capture and storage of solar energy, and the relation between structures and photochemical reactivities of these novel supramolecular systems are discussed in relation to the efficiency of charge separation and charge recombination.

TL;DR: It is shown that both solvated and solid-state COFs enable rapid charge separation and exceptional long-term charge retention, thereby providing a key mechanistic basis to envisage the high potential of donor–acceptor COFs for photoelectric applications.

TL;DR: In this paper, the spectral properties of self-assembled donor-acceptor dyads formed by axial coordination of zinc tetraphenylporphyrin, (TPP)Zn, and fulleropyrrolidine bearing either pyridine or imidazole coordinating ligands were investigated.

TL;DR: In this article, the authors present a review of the molecular level details of natural photosynthesis, particularly the mechanism of light dependent reactions in oxygen evolving organisms, absorption efficiency of solar energy and direct energy production, and demonstrate the concept and examples of the semi-artificial photosynthesis in vitro.

TL;DR: Femto- and nanosecond transient absorption and photoelectrochemical techniques have been employed in these studies to give clear evidence for the occurrence of energy- and electron-transfer reactions and to determine their rates and efficiencies.
