globular macromolecule and its application as a bimolecular catalyst are reported. The macromolecular structure supports (at least) two zinc-metalated porphyrin units, each capable of binding a single reactant. The proximity of the two bound reactants results in an increased local concentration, leading to a maximum 300-fold increase in the reaction rate. In contrast to other synthetic catalysts, where
据报道球形大分子的合成及其作为双分子催化剂的应用。大分子结构支持(至少)两个锌金属化的卟啉单元,每个单元都可以结合单个反应物。两种结合的反应物的接近导致局部浓度增加,从而导致反应速率最大增加300倍。与双齿产物抑制进一步反应的其他合成催化剂相反,该大分子体系使产物被反应物置换,从而导致转化和催化。我们认为,这是由于大分子宿主系统的动力学所致,该系统保持了足够的灵活性以采用有利/反应性的几何结构,
