To develop stretchable and patternable optical paints, a cyanostilbene-based liquid crystal polysiloxane (CSLCP) was newly synthesized. Subsequently, CSLCP was mixed with a small amount of Pt catalyst and inhibitor for a self-crosslinkable curing system. Dried CSLCP paints have smectic mesophase at room temperature, which allows uniaxial orientation and photoisomerization of cyanostilbene moiety in CSLCP. In addition, CSLCP paints are cured by the dehydrocoupling and oxidation reaction with Pt catalyst. Eventually, light-induced optical changes and thermomechanical properties of CSLCP paints were investigated in detail. Using newly developed CSLCP paints, various optical coatings were additionally demonstrated.
