| titleOfInvention | Diarylethene-based compound and production thereof |
| abstract | NEW MATERIAL:A compound shown by formula I (n is 2-5; A is group shown by formula III; B is group shown by formula III; R 1 is alkyl; R 2 to R 5 are H, alkyl or alkoxy; R 6 is alkyl or alkoxy and at least one of R 2 to R 6 is alkoxy). n EXAMPLE: 1-(1,2-Dimethyl-3-indolyl))-2-(2-cyano-3-methoxy-5- methylthienyl)-3,3,4,4,5,5-hexafluorocyclopentene. n USE: Having photochromic properties, suitable for light recording material, etc. n PREPARATION: An indole derivative shown by the formula IV (X 1 is Br or I) is reacted with a thiophene derivative shown by formula V (X 2 is Br or I) and a lithio forming agent such as butyllithium to give an aryllithio substance. This substance is reacted with a perfluoroalkene compound shown by formula VI. n COPYRIGHT: (C)1992,JPO&Japio |
