The ligand 1,2-bis(5-(2-pyridyl)-4H-1,2,4-triazol-3-yl)benzene, H2L, self assembles with CoII to form [Co4(H2L)6]8+} rectangles which mechanically interlock via self-assembly to form a [2]catenane. The catenated structure displays single-molecule magnetism (SMM), highlighting how mechanically interlocked systems can be used to arrange SMM centers in topologically complex arrays.
配体 1,2-bis(5-(2-pyridyl)-4 H -1,2,4-triazol-3-yl)苯 H 2 L与 Co II自组装形成 [Co 4 ( H 2 L ) 6 ] 8+ } 矩形通过自组装机械互锁以形成[2]链环。链状结构显示出单分子磁性 (
SMM),突出了如何使用机械联锁系统将
SMM 中心排列在拓扑复杂的阵列中。
