Solvent-assisted ligand incorporation is an excellent method for the post-synthetic functionalization of Zr-based metal-organic frameworks (MOFs), as carboxylate-derivative functionalities readily coordinate to the Zr nodes by displacing node-based aqua and terminal hydroxo ligands. In this study, a photocatalytically active ruthenium complex Ru(bpy)(dcbpy), that is, bis-(2,2'-bipyridine)-(4,4'-dicarboxy-2,2'-bipyridine)ruthenium, was installed in the mono-protonated (carboxylic acid) form within NU-1000 SALI. Crystallographic information regarding the siting of the ruthenium complex within the MOF pores is obtained by difference envelope density analysis. The ruthenium-functionalized MOF, termed Ru-NU-1000, shows excellent heterogeneous photocatalytic activity for an oxidative amine coupling reaction.
溶剂辅助配体掺入是一种用于锆基金属有机框架(MOF)后合成功能化的出色方法,因为羧酸盐衍生物官能团可通过取代基于节点的水合配体和末端羟基配体,轻松地与锆节点配位。在本研究中,一种具有光催化活性的钌配合物Ru(bpy)(dcbpy),即双(2,2'-联吡啶)-(4,4'-二羧基-2,2'-联吡啶)钌,以单质子化(羧酸)形式安装在NU-1000 SALI中。通过差分包络密度分析获得了有关钌配合物在MOF孔中位置的晶体学信息。这种钌功能化的MOF,称为Ru-NU-1000,在氧化胺偶联反应中表现出出色的多相光催化活性。
