Abstract

The bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligands 1 and 2 were used in the formation of the luminescent di-metallic Tb(III) triple stranded helicates 3 and 4 (L₃Tb₂; L = 1 or 2). Both 3 and 4 were formed in high yield under either kinetic or thermodynamic conditions and their binding constant values were evaluated. The photophysical properties of the assemblies were analysed in the solution and solid state. The morphology of the ligands vs. the Tb(III) assemblies were significantly different as detected by SEM.

由双三叉（1,2,3-三唑-4-基）-吡啶酰胺（tzpa）配体及其高阶自组装体形成的镧系发光双金属三链螺旋体†

双三齿（1,2,3-三唑-4-酰基）吡啶酰胺（tzpa）配体1和2用于形成发光的双金属Tb（III）三链螺旋体3和4 (L3Tb2)；L = 1或2)。3和4在动力学或热力学条件下均以高收率生成，并对它们的结合常数值进行了计算。在溶液和固体状态下分析了组装体的光物理性质。通过扫描电镜（SEM）检测到配体与Tb（III）组装体的形态有显著差异。
