dihydrogen phosphate loadings offer a cooperative complexation mode associated with a positive dendritic effect. In higher dihydrogen phosphate concentrations, the dendritic branches act independently and the binding mode changes to 1:1 anion: complexation site. Despite the anchoring, the dendritic receptors retain the superior efficiency and selectivity of a monomer, paving the way to recyclable receptors
受体结构内基于尿素的结合单元的重复不仅导致单体特性倍增。正如光谱研究、UV-Vis 和1 H-NMR 在经典或竞争滴定模式下所证实的那样,与载体的连接将活性部分分配到预先确定整个受体分子功能的相互位置。二价受体形成自我聚集体。具有低磷酸二氢负载量的树突受体提供了与积极的树突效应相关的协同络合模式。在较高的磷酸二氢浓度下,树枝状分支独立作用,结合模式变为 1:1 阴离子:络合位点。尽管存在锚定,但树突受体仍保留了单体的卓越效率和选择性,为可回收受体铺平了道路,这在经济和生态方面都是理想的。
