Abstract
Boron-containing polymers have been demonstrated to be useful polymeric materials. However, the synthesis of boronic acid- or ester-containing polymers is highly challenging due to their instability and difficult characterization. This paper introduces N-methyliminodiacetic acid (MIDA) as a unique protecting group for the boronic acid to stabilize boron-containing polymers. The synthesized MIDA boronate stabilized polymers show remarkable stability to the air, moisture, and chromatography. Therefore, they could be used as a versatile platform for synthesizing other boronic acid- or ester-containing polymers. Postpolymerization modification also incorporates different functionalities by using this platform by Suzuki–Miyaura coupling. Both stability and versatility make MIDA boronate stabilized polymers have great potential applications in material and biomedical fields associated with borane chemistry.
