Abstract:Photoresponsive liquid crystals are promising materials for sunlightdriven smart windows, which can automatically change their optical states in response to sunlight and control energy flow between the inside and outside of a building. Herein, liquid-crystalline systems are developed that show a transparent-scattering transition upon irradiation with sunlight in a wide temperature range. Push−pull azobenzenes with axial chirality have been newly developed as photochromic chiral dopants to allow changes in meso… Show more
