制备了一系列衍生自稳定自由基、6-氧代过哒嗪和 1,4-二氢苯并[ e ][1,2,4]三嗪-4-基并含有N-甲基咪唑鎓基团的弯曲核顺磁离子液晶,并研究了它们的介晶、磁性和离子导电性能。离子对在 100 °C 以上形成流体近晶相,其中离子层被顺磁层隔开。两种选定衍生物的离子电导率在 10 -5 –10 -8 S cm -1和活化能E a 的范围内约为 1.5 eV。原始固体样品的磁化率测量 (SQUID) 揭示了顺磁性层中类似液体的分子排列和弱反铁磁相互作用。
Novel thiol-terminated bent-core liquid crystals (LCs) are used to decorate gold nanoparticles. Thioacetate or xanthate/xanthogenate functional groups are used to effect the attachment of the LCs to the gold nanoparticles. Such bent-core decorated nanoparticles may be dissolved in bent-core liquid crystal host media to provide polarizable systems which respond quickly to applied electric fields and exhibit other interesting and useful optical and electro-optic behaviour.
