The electron spin dynamics associated with the photoinduced intramolecular electron transfer (ET) in a covalently linked malonate-strapped zinc porphyrin-fullerene (ZnP-C 6 0 ) dyad with "parachute" geometry was studied bytime-resolved electron param

We have synthesized a series of structurally related, covalently linked electron donor-acceptor triads having highly restricted conformations to study the effects of radical ion pair (RP) structure, energetics, and solvation on charge recombination.

Using high time resolution Q-band EPR we have been able to identify three different radical pairs generated by pulsed laser excitation of the fixed distance triad consisting of a zinc-9-desoxo-meso-methylpyrochlorophyllide donor (ZC), a pyromellitimi

Porphyrins and related compounds are basic moieties which upon photoexcitation produce paramagnetic transients important to many processes in biology, material science and light–energy conversion. This short review demonstrates the application of t

We report on a series of electron donor−acceptor (D-A) dyads that undergo singlet-initiated charge separation to produce a strongly spin coupled radical ion pair that subsequently undergoes charge ...

We report on intramolecular electron and/or energy transfer (IET and IEnT), in two photoexcited electrostatically bound dimers: (1) zinc(II) tetrakis(4-sulfonatophenyl)porphyrin and magnesium(II) tetrakis(4-N,N,N-trimethylanilinium)porphyrin, [ZnTSPP

The photoexcited triplet states of the nonplanar porphyrins, free base and zinc 2,3,7,8,12,13,17,18-octaethyl-5,10,15,20-tetraphenylporphyri ns (OETPPs), were examined by laser excitation-time resolved EPR spectroscopy. Measurements were carried out
