中文摘要:

为用在空基于按的多孔的器官的聚合物(H-CPPs ) 的非共有原子价相互作用的转变金属催化剂的 heterogenization 的一条灵巧的途径被介绍。催化地活跃的 cationic 种,[Ru (bpy )3]2+(bpy = 2,2-bipyridyl ) ,经由静电的相互作用在 H-CPPs 被使不能调动。内在的性质[Ru (bpy )3]2+ 很好被保留。当在可见光的照耀下面为 4-methoxyphenylboronic 酸的氧化 hydroxylation 使用了到 4-methoxyphenol 时,产生 Rucontaining 空聚合物展出了优秀催化活动,提高的稳定性,和好再循环能力。吸引人的催化表演主要从有效集体转移和 cationic Ru 建筑群的化学性质的维护导致了 H-CPPs。

英文摘要:

A facile approach for the heterogenization of transition metal catalysts using non-covalent interactions in hollow click-based porous organic polymers (H-CPPs) is presented. A catalytically active cationic species, [Ru(bpy)3]〉 (bpy = 2,2'-bipyridyl), was immobilized in H-CPPs via electrostatic interactions. The intrinsic properties of [Ru(bpy)3]〉 were well retained. The resulting Ru- containing hollow polymers exhibited excellent catalytic activity, enhanced stability, and good recyclability when used for the oxidative hydroxylation of 4-methoxyphenylboronic acid to 4-methoxyphenol under visible-light irradiation. The attractive catalytic performance mainly resulted from efficient mass transfer and the maintenance of the chemical properties of the cationic Ru complex in the H-CPPs.
