Room temperature photochromic liquid crystal [3H]-naphtho[2,1-b]pyrans—photochromism in the mesomorphic state

Abstract

Photochromic liquid crystals based on [2H]-chromenes functionalised in the 3,3′-positions by phenyl groups linked to 4-cyano-4′-hydroxybiphenyl groups via alkyl and siloxane spacers as chromophore were synthesised and the photochromic and mesomorphic behaviour was investigated.
