本文报道了1，2-bis(3-methyl-2-thienyl)perfluorocyclopentene(1)单晶的三维可擦写光记录，它随光致变色反应呈现可逆的荧光变化。通过荧光检测方法读取的记录光点大小在平面上约为200 nm，深度约为1.5um，这对应于高于5TBit/cm(3)的记录密度。用可见光照射，擦除记录的斑点。写入/读取/擦除周期可以重复10(4)次以上。
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.
