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 Ris independently selected from the group consisting of H, or halo; each Ris independently selected from the group consisting of H, halo, a polymer backbone, alkyl or aryl; or, when both Rtogether form &#x2014;CH&#x2550;CH&#x2014; and form part of a polymer backbone; each Ris independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl; each Ris aryl; and each Ris independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl. 

Diarylethene compounds and uses thereof

Variable transmittance optical filters capable of transitioning from a light state to a dark state on exposure to UV radiation and from a dark state to a light state with application of an electric voltage are provided. The optical filters comprise a switching material that comprises one or more chromophores that have electrochromic and photochromic properties.
