Abstract

Novel bisthienylethene-based photochromic material (TAP-BTE), in which four bisthienylethenes link on the ring of tetraazaporphyrin, has been synthesized. This kind of macrocyclic-linked bisthienylethenes has demonstrated better ring-closing quantum yield and has higher absorption cross- sections (1.65 X 10⁴ M^-1cm^-1). The optical switch and fatigue resistance properties of the novel photochromic material have been investigated. The results showed that TAP-BTE has a thermally gated reactivity, and is useful for non-destructive readout when it is used as the memory medium.
