DIARYLETHENE COMPOUNDS AND USES THEREOF
Document Type and Number:
Japanese Patent JP2019123713
Kind Code:
A
Abstract:
To provide novel photochromic/electrochromic compounds with suitable photostationary states or suitable sensitivity indices.SOLUTION: The invention provides a compound reversibly convertible between a ring-open isomer (formula IA) and a ring-closed isomer (IB) according to the formula in the figure. (Z is N, O or S; each Ris H or halo; each Ris H, halo, a polymer backbone, alkyl or aryl, or Rtogether form CH=CH-; each Ris H, halo, alkyl, alkoxy, thioalkyl or aryl; each Ris aryl; and each Ris H, halo, alkyl, alkoxy, thioalkyl or aryl.)SELECTED DRAWING: None
