concerning the synthesis and characterisation of a series of imine derivatives that incorporate the 2-phenylpyridine (2-ppy) core. These derivatives were used in the cyclometalating reactions of platinum(II) or palladium(II) in order to prepare several complexes with liquid crystalline properties. Depending on the starting materials used as well as the solvents employed, different metal complexes were obtained
在这项工作中,我们报告了有关一系列结合了2-苯基吡啶(2-ppy)核心的亚胺衍生物的合成和表征的研究。这些衍生物用于铂(II)或钯(II)的环金属化反应)以制备具有液晶性质的几种配合物。取决于所使用的起始材料以及所使用的溶剂,获得了不同的金属络合物,其中一些在室温下显示出液晶行为和发光性质。已发现,即使有两个竞争的配位位点,环金属化过程也总是在亚胺键断裂的情况下(对于Pt)或不发生(对于Pd)在2-ppy核上发生。我们成功地表明,可以通过改变辅助苯甲酰硫脲(BTU)配体上长的柔性烷基尾部的体积分数,来制备基于双环palpalated杂配体的发射型室温液晶材料。
