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 R
1
is independently selected from the group consisting of H, or halo; each R
2
is independently selected from the group consisting of H, halo, a polymer backbone, alkyl or aryl; or, when both R
2
together form —CH═CH— and form part of a polymer backbone; each R
3
is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl; each R
4
is aryl; and each R
5
is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl.
本发明提供了一种按照式IA和IB的化合物,在光致变色和电致变色条件下,可在环开放异构体A和环闭合异构体B之间可逆地转化。对于取代基,Z为N、O或S;每个R1独立地选自H或卤素;每个R2独立地选自H、卤素、聚合物骨架、烷基或芳基;或者,当两个R2一起形成-CH═CH-并形成聚合物骨架的一部分时;每个R3独立地选自H、卤素、烷基、烷氧基、硫代烷基或芳基;每个R4为芳基;每个R5独立地选自H、卤素、烷基、烷氧基、硫代烷基或芳基。
