Two complementary thermoreversible ABC triblock copolymers containing either phenylboronic acids with low pK_a values or galactosyl groups in the hydrophilic B blocks are synthesized by sequential reversible addition‐fragmentation chain transfer polymerization and subsequent modification of the functional groups. Both ABC triblock copolymers undergo reversible sol‐to‐gel transitions upon temperature change and form physically cross‐linked hydrogels under physiological conditions. Furthermore, the spontaneous adhesion of these thermoreversible hydrogels via the formation of boronic esters between the phenylboronic acid and galactosyl groups under physiological conditions is realized for the first time.

硼酸-糖配位作用对热可逆ABC三嵌段共聚物基水凝胶的宏观粘合

通过顺序可逆的加成-断裂链转移聚合反应和随后的官能团修饰，合成了两种互补的热可逆ABC三嵌段共聚物，它们在亲水性B嵌段中含有低p K _a值的苯基硼酸或半乳糖基。两种ABC三嵌段共聚物在温度变化时都会经历可逆的溶胶-凝胶转变，并在生理条件下形成物理交联的水凝胶。此外，首次实现了在生理条件下通过在苯基硼酸和半乳糖基之间形成硼酸酯来自动结合这些热可逆水凝胶。
