Abstract : Due to the interest in the frequency-domain optical storage application, recent researches on spectral hole-burning concentrated on the two-colour photon-gated persistent hole-burning. Some organic systems have been investigated. A representative one is TZT as a donor and CHCl3 as an acceptor in PMMA film undergoing donor-acceptor electron transfer, which offered a significant mechanism for persistent hole-burning in organic system. But there is an insurmountable problem in the system. AS CHCl3 is volatile at room temperature, its concentration can not be controlled and the sample is difficult to further study. Here we report the hole-burning system composed of metal-tetrabenzoporphyrin derivatives (MTBP) as the donors and a solid electron acceptor, p-hydroxybenzaldhyde (PHBA), which can easily be made into a stable 'dry' film and in which the concentration of each component can be modified easily.
