True Closed‐Loop Recyclable Hydrogels Enabled by Imine Boronic Ester Crosslinking

Advanced Materials, EarlyView.
Subtle molecular differences in imine boronic ester crosslinkers profoundly influence hydrogel properties. 2‐formylphenylboronic acid crosslinkers form previously undisclosed 3‐amino‐benzoxaborole heterocycles, enhancing elasticity despite lower crosslinking density compared to their 4‐formylphenylboronic acid counterparts.
