  Synthesis and Electrochromic Properties of Bis(2-tetrathiafulvalenylethynylphenyl)ethynes

  摘要：

  Bis(2-tetrathiafulvalenylethynylphenyl)ethynes 1a and 1b have been synthesized by the Sonogashira coupling reaction of 4-iodotetrathiafulvalenes with bis(2-ethynylphenyl)ethyne. The dimeric TTFs 1a and 1b form an open-chain anti conformation in the neutral and tetracation states, whereas la and 1b form a helical syn conformation in the mono- and dication states owing to their face-to-face interaction between the two TTF units. Such conformational changes lead to unique electrochromic and on-off switching properties of 1a and 1b in UV-vis-NIR spectra.
