A new family of alkynylated, amphiphilic dendrimers consisting of amidoamine linkers connected to 5,5′‐functionalized 2,2′‐bipyridine cores has been developed and evaluated in the formation of metallodendrimers of different generations and in self‐assembly protocols. A convergent synthetic strategy was applied to provide dumbbell‐shaped amphiphilic dendrimers, where the 2,2′‐bipyridine cores could be coordinated to Fe^II centers to afford corresponding metallodendrimers. The ability of the metallic‐ and non‐metallic dendritic structures to self‐assemble into functional supramolecular aggregates were furthermore evaluated in aqueous solution. Spherical aggregates with sizes of a few hundred nanometers were generally produced, where controlled disassembly of the metallodendrimers through decomplexation could be achieved.

功能性两亲金属树状大分​​子的设计，合成和自组装。

已经开发了一个新的烷基化两亲树状大分子家族，该家族由与5,5'-官能化的2,2'-联吡啶核连接的酰胺基胺连接体组成，并已在不同世代的金属树状大分​​子的形成和自组装方案中得到评估。应用会聚合成策略提供哑铃形两亲树状聚合物，其中2,2'-联吡啶核可与Fe ^II配位中心提供相应的金属树枝状大分子。在水溶液中进一步评估了金属和非金属树枝状结构自组装成功能性超分子聚集体的能力。通常生产尺寸为几百纳米的球形聚集体，其中可以通过分解来控制金属树枝状大分子的分解。
