Abstract: Progress in the study of molecular structure and property relationship of mesogen-jacketed liquid crystalline polymers(MJLCPs) was reviewed. Different from traditional side chain liquid crystalline polymers, MJLCPs have semirigid polymer chain conformation due to the strong interaction between the side chain mesogens and the polymer backbone. Supramolecular liquid crystalline columnar phases are thus formed in most of MJLCPs systems. The self-assembly behavior of the block copolymers containing MJLCPs as rod segments have been studied as well both in melt and in solutions. Lamellar and perforated lamellar microphase separated structures could be found in diblock copolymers, while in solutions micelles with MJLCP core surrounded by the coil corolla were easily formed. Meanwhile, MJLCPs and the related block copolymers could be exploited as the functional materials with unique electro-optical properties. An outlook for the future development in this area is proposed in the last part of this review.

Key words: Mesogen-jacketed liquid crystalline polymer, Supramolecular liquid crystal, Rod-coil block copolymers, Self-assembly
