PHENYLBORONIC ACID MONOMER AND PHENYLBORONIC ACID POLYMER

摘要

Disclosed are a phenylboronic acid monomer and a phenylboronic acid polymer, each of which can have a pKa value suitable for the use under physical environments and can be used for various use applications. The phenylboronic acid monomer has a structure represented by general formula (13) and therefore has high hydrophilicity, can have a satisfactorily low pKa value when the phenyl ring is fluorinated, and can have a polymerizable unsaturated bond. The phenylboronic acid monomer has high hydrophilicity at a pKa value of 7.4 or less which is a physical level, and can be polymerized with a wide variety of monomers to produce polymers suitable for the intended purposes.
