Abstract

Three-dimensional erasable optical recording in a single crystal of 1,2-bis(3-methyl-2-thienyl)perfluorocyclopentene (1), which shows a reversible fluorescence change with the photochromic reaction, has been demonstrated. The recorded spot size read by a fluorescence-detection method was approximately 200 nm in plane and 1.5 mum in depth, which corresponds to the recording density higher than 5 Tbit/cm(3). The recorded spots were erased by irradiation with visible light. The writing/reading/erasing cycle could be repeated more than 10(4) times.
