A compound according to Formula IA and IB, reversibly convertible under photochromic and electrochromic conditions between a ring-open isomer A and a ring-closed isomer B is provided. For substitutent groups, Z is N, O or S; each R1 is independently selected from the group consisting of H, or halo; each R2 is independently selected from the group consisting of H, halo, a polymer backbone, alkyl or aryl; or, when both R2 together form —CH═CH— and form part of a polymer backbone; each R3 is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl; each R4 is aryl; and each R5 is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl.
提供了一种根据式 IA 和 IB 的化合物,该化合物在光致变色和电致变色条件下可在开环异构体 A 和闭环异构体 B 之间进行可逆转换。对于取代基,Z 是 N、O 或 S;每个 R1 独立地选自 H 或卤代;每个 R2 独立地选自 H、卤代、聚合物骨架、烷基或芳基;或者,当两个 R2 一起形成 -CH═CH- 并构成聚合物骨架的一部分时;每个 R3 独立地选自由 H、卤素、烷基、烷氧基、硫代烷基或芳基组成的组;每个 R4 是芳基;每个 R5 独立地选自由 H、卤素、烷基、烷氧基、硫代烷基或芳基组成的组。
