This invention discloses a photochromism thiophene pyrrole series parallel type perfluoro-cyclopentene compound and its preparation and usage. This photochromic material can maintain satisfactory photochromism performance either in solution or thin film, and both open loop state (colourless state) and closed loop state (coloration state) have high performances such as very good chemistry and heatstability, significant fatigue resistance, higher cyclization quantum yield and very good sensibility and so on. Its open loop state between 350-450nm has fairly high fluorescence, but closed loop state does not have fluorescence. Consequently it can be used for fluorescence detection and fluorescence photoswitch, and is successfully used for high-density hologram optical storage. Its storage attribute is erasable photon storage.
