W e propose a n application in optical data storage of tetraphenylethene doped photopolymer, which has the attribute of aggregation induced emission . We added some divinylbenzene in the photopolymer matrix in order to increase the fluorescence signal contrast The photopolymer host was induced photochemical reaction at the focal point of a high numerical aperture lens. Thu s, w e could record binary data points inside the TPE doped photopolymer matrix through two photon absorption effect experiment. W e got strong signal contrast between the e xposure regions and the non exposure regions This attribute paves a new way for optical data storage and opens the way to exploring the possibility of uti lizing the TPE doped photopolymer as chemical sensors and components of organic light emitting diodes..
