## Abstract A novel photo‐driven liquid crystal (LC) cell was fabricated by sandwiching nematic LC molecules between two quartz plates whose surface was modified with 4‐hexyloxy‐4′‐undecanyloxyazobenzene (6Az11)‐grafted ladderlike copoly(methylhydrosilsesquioxane) (PMHSQ). Reversible changes of the
## Abstract In comparison with our previous work^1^, the stability of the command layer based on an azobenzene‐grafted ladderlike copoly(hydromethylsilsesquioxane) (PMHSQ) coated on quartz plates, is improved evidently by linking through a coupling reagent (triethoxyvinylsilane) to the backbone. Th
