WebThis initial charge separation yields a positive charge on P and a negative charge on the BPh. This process takes place in 10 picoseconds (10 −11 seconds). The charges on the P + and the BPh − could undergo charge recombination in this state, which would waste the energy and convert it into heat. Several factors of the reaction center ...

WebJan 1, 2012 · This state was clearly detected in the early ultrafast experiments, however it turned out that the intervening momomeric BChl L (for a while erroneously designated an “accessory” or “voyeur” pigment) was in fact the true primary acceptor, with the first charge separation, P + BChl L −, occurring in 3 ps (Fig. 2 step 1a). WebMar 21, 2024 · The repeating unit functions as both a donor–acceptor pair and a dual-redox site to realize a molecule-level coupling of intramolecular charge separation (τCS = 136.2 ps, τCR = 949 ps) and reversible redox chemistry (C=O/C O−, TPA/TPA+).
