Abstract

This work illustrates the remarkable ability of amine-terminated PAMAM dendrimers to entrap multiple guest molecules. While previous encapsulation studies with dendritic polymers demonstrated multi-dye uptake, the dendrimers required extensive synthetic modification. This study utilizes unmodified PAMAM dendrimers to encapsulate multiple phenol blue molecules. Quantitative data on the uptake capacity and robustness of association is presented.

摘要

这项工作展示了胺基封端的聚酰胺-胺（PAMAM）树枝状大分子捕获多个客体分子的卓越能力。虽然先前关于树枝状聚合物的包封研究证明了多染料摄取，但树枝状大分子需要大量的合成修饰。本研究利用未修饰的PAMAM树枝状大分子来包封多个酚蓝分子。给出了关于摄取能力和结合稳定性的定量数据。
