摘要

Two series of banana-shaped liquid crystalline (LC) H-bonded complexes HPm/CBn (i.e., bent-core H-bonded side-chain homopolymer HP mixed with bent-core covalent-bonded small molecule CB)and CP m/HBn i.e., bent-core covalent-bonded side-chain homopolymer CP mixed with bent-core H-bonded small molecular complex HB) with various m/n molar ratios were developed. The bent-core covalent-and H-bonded structural moieties were homopolymerized in the banana-shaped LC H-bonded complexes HPm/CBn and CPm/HBn, respectively. The influences of m/n molar ratios (polymeric moieties vs. small molecular moieties) on the mesomorphic and electro-optical properties of both banana-shaped LC H-bonded complexes HPm/CBn and CP m/HBg were investigated. The polar smectic phases could be achieved and stabilized by smaller contents of polymeric dopants in banana-shaped LC H-bonded complexes, such as HP1/CB10, HP1/ CB15, CP1/HB10,and CP1/HB15, which possessed tunable spontaneous polarization (Ps) values according to the molar ratios of m/n,thatis, lower Ps values obtained in H-bonded complexes HPm/CBn and CPm/HBn with higher ratios of H-bonded moieties (larger m/n molar ratios), respectively.
