Acetylene Polymers and Their Use as Liquid Crystals

总结: 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.

技术优势: 1. Provides rigid polymeric backbone with conductivity and molecular orientability
2. Soluble and fusable
3. Thermally stable
