Two colour photon-gated persistent spectral hole-burning via donor-acceptor electron transfer is reportedin systems where the donor: zinc tetraphenylporphyrin (ZnTPP) and the acceptor: vinylbenzylchloridewhere linked to a polystyrene chain. A spectral hole is observed when the sample is irradiatedusing a gating light in addition to the wavelength-selective light. No effect of the gating light has beenobserved for ZnTPP dispersed in polystyrene (PS) even with efficient acceptors. In contrast, the efficiencyof hole formation under two colour excitation is four times larger than that under one colour excitationin ZnTPP-PBCS/PMMA and nearly two times larger in ZnTPP-PBCS/PS.
