“…[6][7][8] Up to now, MJLCPs based on 2,5-disubstituted styrene have been synthesized and investigated. A series of MJLCPs based on 2-vinylhydroquinone (VHQ), 2-vinyl-1,4-phenylenediamine (VPDA), 2-vinylterephthalic acid (VTA), 6,[9][10][11][12][13][14] vinyl terphenyl (VTP), [15][16][17][18] and with oxadiazole, [19][20][21] have been successfully designed and synthesized (see Scheme 1). Most of the mesogenic groups contain functional groups (such as ester or amide links) which rule out some synthetic strategies, such as anionic and cationic polymerization.…”

The controlled radical polymerization of mesogen‐jacketed liquid crystalline polymers has triggered great interests in synthesis of complex structures as well as well‐defined linear homopolymers with controlled molecular weight and narrow molecular weight distributions. This review highlights the synthetic strategies of controlled radical polymerization of linear homopolymers, star polymers, superbranched polymers, graft polymers, block copolymers, star block copolymers, and so on. The employed living methods include nitroxide‐mediated radical polymerization and atom transfer radical polymerization. © 2008 Wiley Periodicals, Inc.

Poly{2,5-bis[(4-butoxyphenyl)-oxycarbonyl]styrene} (PBPCS) with a re-entrant phase behavior is used to synthesize a new kind of ABC triblock copolymers (triBCPs), poly. Two well-defi ned triBCPs D 120 S 100 B 50 and D 120 S 100 B 120 with different molecular weights (MWs) and narrow MW distributions are synthesized by sequential atom transfer radical polymerization. The volume fractions of PDMS, PS, and PBPCS in D 120 S 100 B 50 are 0.24, 0.26, and 0.50, respectively, while the values in D 120 S 100 B 120 are 0.14, 0.16, and 0.70, respectively. At low temperatures, PBPCS is amorphous. Both samples form a core-shell hexagonally packed cylindrical (CSH) morphology. At high temperatures, PBPCS in the triBCPs can form a liquid crystalline (LC) phase, the transformation of which can induce an order−order transition (OOT) of D 120 S 100 B 120 . The nanostructure changes from a CSH structure to a three-phase-four-layer lamellar structure, and the transition is thermoreversible. The sequence of the OOT is opposite to that of a coil−coil−coil triBCP. The unusual LC behavior of PBPCS plays an important role on the thermoreversible morphological transition of the triBCP.

Matters comprise of molecules that exist in three different phases-solids, liquids and gases depending on their arrangement. The arrangement of molecules in a crystalline solid leads to long-range positional and orientational orders. In isotropic liquid, on the other hand, the molecules are arranged randomly and possess no order and flow freely. However, it was observed that a certain class of molecules organise in a different manner in order to exhibit a new phase, popularly known as liquid crystalline phase. Molecules in liquid crystalline phase self-organize, leading to positional/orientation order. Macroscopically, the liquid crystalline phase exhibits flow and appears like an opaque fluid.
