A 1:3 molar complex of the fluoroalkyl side chain-substituted 2,6,10-tris-carboxymethoxy-3,7,11-tris(4,4,5,5,6,6,7,7,7-nonafluoroheptyloxy)triphenylene (TPF4) with the second generation dendron 3,5-bis(3,4-bis-dodecyloxybenzyloxy)-N-pyridin-4-yl-benzamide (DN) assembled through complementary hydrogen bonding to form a supramolecular columnar liquid crystal, which exhibited homeotropic alignment when sandwiched between octadecyltrichlorosilane (OTS)-coated or indium tin oxide (ITO)-coated glass plates due to specific interactions between the fluoroalkyl side chains and the substrates.
一种1:3摩尔比的复合物,由氟代烷基侧链取代的2,6,10-三羧甲氧基-3,7,11-三(4,4,5,5,6,6,7,7,7-九氟庚氧基)并三苯(TPF4)与第二代树枝状分子3,5-双(3,4-双十二烷氧基苄氧基)-N-吡啶-4-基-苯甲酰胺(DN)通过互补氢键组装形成超分子柱状液晶。该液晶在夹置于十八烷基三氯硅烷(OTS)涂层或铟锡氧化物(ITO)涂层玻璃板之间时,由于氟代烷基侧链与基底之间的特定相互作用,呈现出均质排列。
