Competition and Promotion between Two Different Liquid-Crystalline Building Blocks: Mesogen-Jacketed Liquid-Crystalline Polymers and Triphenylene Discotic Liquid Crystals

Abstract: Mesogen-jacketed liquid-crystalline polymers (MJLCPs) containing two triphenylene (Tp) units in the side chains, denoted as PPnV (n = 3 or 6, which is the number of the methylene units between the terephthalate core and Tp moieties in the side chains), were synthesized through conventional free radical polymerization, and the phase behaviors of these new combined main-chain/side-chain liquid-crystalline (LC) polymers were investigated. The chemical structures of the monomers were confirmed by elemental analysi… Show more

“…Similar hierarchically ordered nanostructures are obtained by altering the calamitic mesogen from biphenyl to azobenzene . A similar molecular design incorporates triphenylene (Tp), a model discotic mesogen, into the side chains of PDAVT in our previous study . Tp moieties and the terephthalate core are linked via 3 or 6 methylene units as flexible spacers (polymers denoted as PP n V, n = 3 or 6).…”

“…15,16 MJLCPs are rod-like polymers with excellent tunability, 14,17 and they have also been used as rod blocks in constructing block copolymers with various self-assembled structures. 18−21 Polyhedral oligomeric silsesquioxane (POSS), which is often regarded as the smallest silica nanoparticle with a diagonal length of approximately 1.0 nm, is a versatile nanobuilding block that is rigid and shape persistent with various peripheral functionalities.…”

“…Two series of Tp-containing polyacetylenes with different peripheral chain lengths [34] and with different flexible spacers [36] show a typical hexagonal (Φ H ) phase. A series of mesogenjacketed liquid crystalline polymers (MJLCPs) containing two Tp units with different lengths of the methylene units between the terephthalate core and Tp moieties in the side chains can exhibit a variety of LC phases with variation of temperature [37,38] .…”
