    Tolane liquid crystals with piperidine, 3,3,4,4,5,5-hexafluoropiperidine as end group: Synthesis and properties
    摘要:
    A series of new tolane liquid crystals with piperidine and 3,3,4,4,5,5-hexafluoropiperidine as their terminal groups were synthesized via Sonagashira reaction by using Pd(PPh3)(2)Cl-2/Cul as the catalyst. Their structures were modified by varying the terminal N-heterocycles and/or the length of the alkyl/alkoxy chains on the benzene ring. Most of these new compounds exhibit Smectic B or G mesophases, good thermal stabilities and high clearing points. The molecule C(2)H(5)O6F with 3,3,4,4,5,5-hexafluoropiperidine as the end group has a broader HOMO-LUMO energy gap and higher oxidation potential than piperidine derivative C(2)H(5)O6H. The result indicates that the oxidation resistance of the tolane liquid crystals was improved by introducing the terminal fluorinated piperidine. (C) 2015 Elsevier B.V. All rights reserved.

    A series of new fluorocarbon and hydrocarbon N-heterocyclic (C-5-C-7) difluorooxymethylene-bridged liquid crystals have been prepared. The impact of ring (C-5-C-7) as end group was investigated. Compounds with terminal N-heterocyclic 5- or 6-membered rings such as 3,4-difluoropyrrole, pyrrolidine, or pyridine, exhibited nematic phases (N). Whereas the terminal 3,3,4,4-tetrafluoropyrrolidine and 3,3

    A new class of benzodioxocycloalkane‐based (C8–C10) liquid crystals were prepared. The impact of ring (C8–C10) as end group was investigated. The 8–9 membered ring derivatives, 3a–3b, exhibited the nematic phases (N). The mesomorphic behaviors were weakened with increasing the size of the ring. For the ?uorinated medium ring (C8–C10) 3d–3f, it was found only the fluorinated ten membered ring 3f showed

    A series of novel ester liquid crystals with piperidine or 3,3,4,4,5,5-hexafluoropiperidine as terminal group have been prepared in good yield. Some of the new compounds show broad mesomorphic phase range and good thermal stability.

    lmethylmorpholin-3-ones are obtained from a new single step, preparative route by reacting triethylene glycol di(trifluoromethanesulfonate), which contains poly –CF2O– groups, with benzylamine. Reaction of trifluoromethylsulfonate and trifluoromethoxy derivatives with benzylamine gave either the nucleophilically-substituted product or the product resulting from the basic hydrolysis of the difluoromethoxy
