摘要： A rewritable photochromic optical disk comprises a photochromic recording layer made of a dibenzothienyl ethene derivative, 1,2-di(2-cyano-3-benzothienyl)-1,2-dicyanoethene capable of assuming first and second states, the first state with a first absorption band transforming into the second state with a second absorption band by irradiating a first light beam of a first wavelength, and the second state transforming into the first state by irradiating a second light beam of a second wavelength in the second absorption band. This rewritable photochromic optical disk has a stability in the repeated recording and erasing information and a high thermal stability and capable of storage of information extended over a long period of time, in accordance with its higher quantum yield than that of the conventional dibenzothienyl ethene derivative so that the achromatic reaction takes place by irradiation of a low power laser beam.
摘要翻译：可重写的光致变色光盘包括由二苯并噻吩基乙烯衍生物制成的光致变色记录层，能够呈现第一和第二状态的1,2-二（2-氰基-3-苯并噻吩基）-1,2-二氰乙烯酮，第一状态为第一吸收带通过照射第一波长的第一光束并且通过在第二吸收带中照射第二波长的第二光束而转换成第一状态而通过第二吸收带转变成第二状态。这种可重写的光致变色光盘根据其比常规二苯并噻吩乙烯衍生物的量子产率更高，具有重复记录和擦除信息和高热稳定性的稳定性，并且能够长期地延长信息的存储。消色差反应通过低功率激光束的照射进行。
