[Formula: see text] and [Formula: see text], respectively. However, their detailed phase structures were not revealed in the previous works. In this work, we have synthesized a series of novel sandwich-type phthalocyanine-based terbium complexes, bis[2,3,9,10,16,17,23,24-octakis(3,4-dialkoxyphenoxy)phthalocyaninato]terbium(III) ([( C n O )2 PhO ]8 Pc }2 Tb , n = 8–16) (2). Their mesomorphic properties have
我们在之前的工作中发现夹心型酞菁基稀土金属配合物双[2,3,9,10,16,17,23,24-octakis(3,4-dialkoxyphenoxy)phthalocyaninato]lanthanoid(III ) ([( Cn○)2磷]8个人电脑 }2M, M = Eu 和 Lu, n = 8-16) (1 和 3), 表现出两个热致立方中间相 Cub1和幼崽2,以及柱状中间相。盘状液晶化合物很少显示立方中间相。我们揭示了它们对低温 Cub 的对称性1中间相和更高温度的 Cub2中间相分别为[公式:见正文]和[公式:见正文]。然而,它们的详细相结构在以前的作品中没有透露。在这项工作中,我们合成了一系列新型夹心型酞菁基铽配合物,双[2,3,9,10,16,17,23,24-八(3,4-二烷氧基苯氧基)酞菁]铽(三)([(Cn○)2磷]8个人电脑 }2Tb , n = 8-16) (2)。已经使用偏光显微镜、DSC
