通过经由超分子相互作用组装结构简单的部件而产生的超分子组装体提供了开发具有层次复杂性的功能材料的机会。在这里,我们报道了一种基于具有可调节的分层结构和特性的金属有机笼子的超分子凝胶的组装方法。具有24个胆固醇基团的Pd 12 L 24笼(L是胆固醇基官能化的3,5-双(4-吡啶基)苯)被用作超分子构建单元和分子平台,用于具有可调功能行为的功能化。钯12 L 24笼状结构自发地自组装成凝胶,其中凝胶作用涉及正交的金属-有机配位和胆固醇-胆固醇的相互作用。Pd 12 L 24笼子响应温度,在溶液状态和聚集的凝胶状态之间表现出可逆的转变。氘化溶剂和四甲基硅烷很少调节胶凝作用和机械性能。通过改变Pd 12 L 24的胆固醇基含量,可以调节凝胶材料的机械性能。可以在笼子上引入功能性部分(例如,发光TPE基团),并且在保持结构的同时发光性质改变。钯12 L 24 凝胶显示出由分层结构引起的可见的阴离子响应行为。

challenging to investigate the dynamics of coordination-driven self-assembly due to the existence of multiple intermediates and many possible processes. By taking advantage of the high sensitivity and efficiency of fluorescence-resonance energy transfer (FRET), FRET was successfully employed to real-time monitor the dynamic behavior of coordination-driven self-assembly. The Förster energy transfer

Well‐defined thiophene‐coated functional nanospheres were synthesized by instantaneous self‐assembly of twelve 90° PdII‐containing compounds and twenty‐four 120° organic bidentate ligands in acetone. This solvent system was efficient to prepare the self‐assembled complexes, facilitating isolation and purification. The self‐assembled functional nanospheres exhibited interesting electrochemical properties

A double metallacycle was prepared via the size-selective integrative self-sorting of four different building blocks driven by a reversible metal–ligand coordination interaction. A hydrophobic dendron was placed on a metallacycle and a hydrophilic dendron was attached to the other metallacycle, producing a two-faced Janus-type supramolecule with two distinct functionalities. In aqueous media, hierarchical
