Abstract

In our previous works, some holeburning results in organic materials with charge transfer were given. We achieved the photon-gated holeburning in a system containing the electron acceptor (p-hydroxybenzaldhyde (PHBA)) and the electron donor (Zn-tetraphenylbenzoporphyrin (Zn-TPBP) doped in a matrix (poly-methylmethacrylate (PMMA) ) [1-3]. In this paper, we will report the single photon holeburning at 25K in p- tetraphenylporphyrin (TPP) embedded in the matrix of polymethylcellulose. The mechanisms of holeburning and holefilling are discussed.
