Europium‐induced self‐assembly of ligands having a C3‐symmetrical benzene‐1,3,5‐tricarboxamide core results in the formation of luminescentgels. Supramolecular polymers are formed through hydrogen bonding between the ligands. The polymers are then brought together into the gel assembly through the coordination of terpyridine ends by EuIII ions (blue dashed arrow: distance between two ligands in the strand direction)
Eu III,难题的最后一部分: induced诱导的具有C 3对称苯-1,3,5-三甲苯酰胺核心的配体的自组装导致形成发光凝胶。超分子聚合物是通过配体之间的氢键形成的。然后通过三联吡啶末端与Eu III离子的配位,将聚合物聚集成凝胶组件(蓝色虚线箭头:两个配体在链方向上的距离)。

hydrogel templates. Controlled growth of gold nanoparticles at spatially arranged locations along the nanofiber is achieved by UV reduction of Au(I) ions on the supramoleculartemplates. The resulting materials were found to have significant interparticle interactions and well-defined helicity to provide high quality, chiroptically active materials. With this novel approach, the tailored assembly of nanoparticle
