Abstract
A new class of 120 degrees dendritic di-Pt(II) acceptor subunits has been designed and synthesized, from which six-component hexagonal metallodendrimers were easily formed with 120 degrees dendritic dipyridine donors via [3 + 3] coordination-driven self-assembly. The structures of all metallodendrimers are confirmed by multinuclear NMR, ESI-TOF-MS/ESI-FTMS, and elemental analysis. MMFF force-field simulations indicates that all metallodendrimers have a hexagonal ring with an internal radius of approximately 1.4 nm.
摘要
设计并合成了一类新型的120°树枝状二铂（II）受体亚基，通过[3 + 3]配位驱动的自组装，可轻松地将其与120°树枝状二吡啶供体形成六组分六角形金属树枝状大分子。所有金属树枝状大分子的结构均通过多核NMR、ESI-TOF-MS/ESI-FTMS和元素分析得以确认。MMFF力场模拟表明，所有金属树枝状大分子均具有内径约为1.4 nm的六角环。
