Acetylene Polymers and Their Use as Liquid Crystals
A variety of new mesogen-containing acetylenes are prepared and designed. A research team at the HKUST developed new catalyst systems for polymerizing the functional acetylene monomers and manufactured the novel liquid crystalline polyacetylenes. In this new invention, the new side-chain liquid crystalline polymers (SCLCPs) thus manufactured possess the rigid polyacetylene backbones. They demonstrate that the rigid polymer backbone in a properly designed SCLCP system can play an active role in promoting and maintaining the molecular orientations induced by the simple mechanical perturbations.
1. Provides rigid polymeric backbone with conductivity and molecular orientability
2. Soluble and fusable
3. Thermally stable
