With its facile synthesis, the pyridine–1,2,3-triazole chelate is an attractive building block for coordination-driven self-assembly. When two such chelates are bridged by a spacer and exposed to cations of octahedral geometrical preference, they generally self-assemble into dinuclear triple-stranded structures in the solid state and in solution in the presence of non-coordinating counter-ions.

吡啶–1,2,3-三唑螯合物易于合成,是由配位驱动的自组装的诱人构建基。当两个这样的螯合物通过间隔基桥接并暴露于八面体几何偏好的阳离子时,它们通常以固态和在非配位抗衡离子存在下的溶液中自组装成双核三链结构。在解决方案中,取决于间隔物的性质,仍然可以形成更广泛的架构。因此,提出了对间隔基和取代模式的系统研究,它可以评估影响吡啶-1,2,3-三唑螯合物周围自组装的各种因素,以及这些结构中的立体化学控制。讨论了手性,磁性和系统选择的应用,其中涉及Fe(II),Ni(II),Zn(II)和Cu(I)阳离子。
