Applications Using the Metal Affinity of Polyphenols with Mussel- Inspired Chemistry.

Multi-functionality plays a decisive role in tuning and improving fundamental properties of active molecules, and grafting polymerization/conjugation development imparts properties of active molecules to the backbones. Recently, metal-polyphenol coordination networks have attracted a great deal of attention. A variety of transition metal ions can freely combine with catechol/keto-enol containing polyphenols to form metal-polyphenol networks. Herein, the recently studied conjugated polyphenols were summarized and compared to dopamine-conjugated polymers with evaluation of their properties and gelation behaviors. The biomimetic understanding of bioinspired adhesion, metal ion coordination of hydroxyl groups, and their rearrangement within aglycone could expand the ability for the development of biomimetic, eco-friendly, and biocompatible polymers.
