Nanogels with Metal‐Organic Cages as Functional Crosslinks

Abstract

A dinuclear metal‐organic cage with four acrylate side chains was prepared by self‐assembly. Precipitation polymerization of the cage with N‑isopropylacrylamide yielded a thermoresponsive nanogel. The host properties of the cage were retained within the gel matrix, endowing the nanogel with the capability to serve as a sorbent for chloride ions in water. Moreover, a heteroleptic cage with the drug abiraterone as co‐ligand was integrated into a nanogel. The addition of chloride ions induced a structural rearrangement of the metal‐ligand assembly, resulting in the gradual release of abiraterone.
