Systematic variation of the molecular symmetry in a photochromic system based on a 1,2‐bis(2‐methylbenzo[ b ]thiophen‐3‐yl)hexafluorocyclopentene group, connected by decyl spacers to two cyanobiphenyl groups as mesogens, allows for a systematic investigation of the correlations between molecular shape and symmetry, electronic effects, photochromic conversion and liquid‐crystalline properties.
