We report a new system of organic materials for photon-gated persistent spectral hole burning by donor-acceptor electron transfer:a tetrabenzoporphyrin derivative as donor and one of several aromatic cyanides as an acceptor in a poly(methyl methacrylate)(FMMA)host matrix.Up to 50C%deep spectral holes in transmission were burnt and appeared very high hole burning efficiency.
