提出了一种利用中空点击型多孔有机聚合物（H-CPPs）中非共价相互作用使过渡金属催化剂多相化的简便方法。通过静电作用将具有催化活性的阳离子物种[Ru（bpy）3]2+（bpy = 2，2 '-bipyridine）固定在H-CPPs中。[Ru（bpy）3]2+的本征性质得到了很好的保留。所得含钌中空聚合物表现出优异的催化活性，增强的稳定性，和良好的可回收性时，用于氧化羟基化4-甲氧基苯硼酸4-甲氧基苯酚在可见光照射下。这主要是由于H-CPPs中钌配合物的有效传质和化学性质的保持。
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]2+(bpy = 2,2’-bipyridyl), was immobilized in H-CPPs via electrostatic interactions. The intrinsic properties of [Ru(bpy)3]2+were well retained. The resulting Rucontaining 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.
