An ethynyl-substituted nickel(II) phthalocyanine has been synthesised and its thermotropic properties studied; optical microscopy, differential scanning calorimetry (DSC) and X-ray diffraction (XRD) techniques revealed an unusual mesomorphic behaviour observed for the first time in phthalocyanine systems where each disk of the hexagonal columnar mesophase is formed by two ethynyl-substituted phthalocyanine units.
通过光学显微镜、差示扫描量热仪 (
DSC) 和 X 射线衍射 (XRD) 技术,我们合成了一种
乙炔基取代的
酞菁镍(II),并研究了它的趋热特性,发现在
酞菁体系中首次出现了一种不寻常的介形行为,即六方柱状介相的每个圆盘都是由两个
乙炔基取代的
酞菁单元形成的。
