CnH2n+1 with n = 12, 14, 16, and 18), are reported. Upon heating, a phase transition sequence of Cr → SmC → Cub → SmA → isotropic liquid is observed for all of these compounds. Depending on the alkyl chain length, two types of cubic phases are found in this series of compounds. Those with shorter alkyl chains (n = 12 and 14) exhibit a micellar cubic phase, whereas long alkyl chains (n =16 and 18) show
四核三唑银金属致孔菌,[Ag 4(L 4 -C n)6 ] [BF 4 ] 4(L 4 -C n = 4-烷基-1,2,4-三唑,其中C n代表据报道C n H 2 n +1,其中n= 12、14、16和18。加热后,观察到所有这些化合物的Cr→SmC→Cub→SmA→各向同性液体的相变顺序。根据烷基链的长度,在这一系列化合物中发现了两种类型的立方相。那些具有较短的烷基链(Ñ= 12和14)呈现胶束立方相,而长烷基链(n = 16和18)显示双连续立方相。由于存在三维离子传输通道,在[Ag 4(L 4 -C 16)6 ] [BF 4 ] 4的双连续立方中间相上观察到了优异的离子电导率。掺杂少量的AgBF 4可能会通过促进通道中Ag I离子的迁移而显着增强离子传导。
