四氟硼酸镍溶液与2-吡嗪甲酸反应生成了一个单核配位化合物[Ni(Pz)2](Pz=2-pyrazinecarboxylatic acid)。配合物结构中的单核单元通过T…π堆积作用相互联系在一起,进而向二维空间伸展,构成了配合物[Ni(Pz)2]的二维超分子结构。对配位化合物[Ni(Pz)2]光致发光性能的研究发现,配合物[Ni(Pz)2]又展示出了一个大概位于433 nm的宽阔的发射峰。其荧光发射机理被归属为配体内部的π-π*电子跃迁。
The solution reaction of Ni(BF4).6H2O with 2-pyrazinecarboxylatic acid(Pz) yielded a mononuclear complex [Ni(Pz)2].The mononuclear units are further linked by T…π stacking interaction into a 2-D supra-molecular layer.The fluorescent features of the compound show a broad emission peak at ca.433 nm,which is assigned to π…π*intraligand transition of Pz.
