Photoinduced electron transfer (PET) is an excited state electron transfer process by which an excited electron is transferred from donor to acceptor. Due to PET a charge separation is generated, i.e., redox reaction takes place in excited state (this phenomenon is not observed in Dexter electron transfer). See more Such materials include semiconductors that can be photoactivated like many solar cells, biological systems such as those used in photosynthesis, and small molecules with suitable absorptions and redox states. See more It is common to describe where electrons reside as electron bands in bulk materials and electron orbitals in molecules. For the sake of expedience … See more The reverse process to photoinduced electron transfer is displayed by light emitting diodes (LED) and chemiluminescence, where potential gradients are used … See more In many photo-productive systems this charge separation is kinetically isolated by delivery of the electron to a lower energy conductor attached … See more WebJan 8, 2016 · The photoinduced electron transfer reactions bringing about radical and cationic species to initiate corresponding polymerizations can be realized utilizing … WebMar 4, 1999 · We reasoned that the radical ions formed by electron transfer from photoexcited 1 to an acrylate, or subsequent radical products, could initiate the … smanicato north sails
