Alternating isomerization of pseudo-rhodamine and its ultrafast electrochromic video display.

ABSTRACT: As an eye-friendly display technology, electrochromic displays still face challenges in playing videos due to their slow response speed. Here, we designed and developed pseudo-rhodamine electrochromic molecules through a "tandem all-in-one" synthetic strategy that covalently integrates three distinct functional units within a single molecule. This molecular architecture simultaneously achieves exceptionally high heterogeneous electron transfer rate constant and ultrahigh molar absorption coefficient. We verified the underlying electrochromic mechanism involving a two-electron redox process of pyridinecarboxylic acid derivative units coupled with reversible pseudo-rhodamine spirocyclization. By implementing this tandem all-in-one molecular engineering strategy, different functional subunits
