Abstract:Two colour photon-gated persistent spectral hole-burning via donor-acceptor electron transfer is reported
in systems where the donor: zinc tetraphenylporphyrin (ZnTPP) and the acceptor: vinylbenzylchloride
where linked to a polystyrene chain. A spectral hole is observed when the sample is irradiated
using a gating light in addition to the wavelength-selective light. No effect of the gating light has been
observed for ZnTPP dispersed in polystyrene (PS) even with efficient acceptors. In contrast, the efficiency… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
