[L2Cu4I4]n (1) based on a cubic [Cu4I4] node and ditopic, bridgingbis(triazole) (L = 2,6-bis((1H-1,2,3-triazol-1-yl)methyl)pyridine) is a unique and highly symmetric cubane cluster based coordinationpolymer with strong yellow emission. Comparison with similar coordinationpolymers permits a structure activity relationship and reveals that the emission energy for these [Cu4I4] cluster-based materials
[L 2 Cu 4 I 4 ] n(1)基于立方[Cu 4 I 4 ]节点和对位,桥接双(三唑)(L = 2,6-bis((1 H -1,2,3-三唑-1-基)甲基)吡啶)是一种独特的,高度对称的基于古巴簇的配位聚合物,具有强黄色发射。与类似配位聚合物的比较允许结构活性关系,并揭示这些[Cu 4 I 4 ]团簇材料的发射能量出现在Cu⋅⋅⋅Cu距离和四面体几何指数值的中间范围。
