Borinic acid block copolymers have been prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization and investigated as “smart materials” in sensory applications. Taking advantage of the hydrogen bond donating ability of the borinic acid groups, supramolecular aggregates of PNIPAM-b-PBA were generated by complexation with P4VP. The P4VP complex showed greatly improved fluoride ion detection efficiency relative to the PBA polymer by itself. The block copolymer PS-b-PBA was processed into porous films with tunable pore size by drop-casting from THF in the presence of trace amounts of water. A microporous polymer film that was deposited on an electrode was utilized as a biosensor for acetylthiocholine chloride detection after immobilization of acetylcholine esterase.
