Dimeric Tetrathiafulvalene Linked to <i>pseudo‐ortho‐</i>[2.2]Paracyclophane: Chiral Electrochromic Properties and Use as a Chiral Dopant

Abstract

A dimeric tetrathiafulvalene installed into a chiral pseudo-ortho-[2.2]paracyclophane framework was synthesized as a novel chiral electrochromic material. This compound exhibited pronounced chiroptical properties in the UV-Vis-NIR range depending on its redox states without racemization. Each enantiomer was examined as a chiral dopant for nematic liquid crystals (LCs), and the induced helicity of the LC solvent was in accord with that of the tetrathiafulvalene compound.
