Temperature‐ and Light‐Regulated Liquid Crystal Smart Window for Dynamic Control of Daylight and Solar Heat in All‐Weather Conditions

Angewandte Chemie, EarlyView.
An environmentally adaptive smart window based on the interplay of light‐driven molecular motors and liquid crystal (LC) polymers is developed. The window can dynamically switch among three distinct working states: transparent, reflective, and scattering, depending on ambient temperature and solar light intensity, enabling excellent modulation of ...
