Synthesis and mesomorphic properties of 1,1-difluoroalkyl-substituted biphenylthienyl and terphenyl liquid crystals. A comparative study of mesomorphic behavior relative to alkyl, alkoxy and alkanoyl analogsElectronic supplementary information (ESI) available: experimental details for compounds 4, 9, 10, 12, 15–19, 25–39, 45 and 49.

摘要:
制备了一系列含有1,1-二氟戊基末端基团的联苯并噻吩型和三联苯型液晶材料。将这些化合物的液晶性能与CF2基团被-CH2-、-O-或-CO-基团替代的类似物的性能进行了对比。1,1-二氟烷基具有独特的行为,倾向于促进正交层状相行为。
