WebApr 1, 2024 · Ultrafast Photoinduced Electron Transfer in a Photosensitizer Protein. Photosystem II (PSII) is a large membrane protein (∼700 kDa) complex, harboring P680 +, … 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 the following description will be … See more The reverse process to photoinduced electron transfer is displayed by light emitting diodes (LED) and chemiluminescence, where potential gradients are used to create excited states that decay by light emission. See more In many photo-productive systems this charge separation is kinetically isolated by delivery of the electron to a lower energy conductor attached to the p/n junction or into an See more WebPhotoinduced electro n-transfer is a subject that has received intense study.1-3 Absorption of a photon produces an excited state that may have an amount of charge transfer va rying from very little to almost complete, althou gh electron transfer may also follow photoexcitations that produce little charge transfer in the initial step. hierarchical band stimulsoft
