Development　of　hydrogel-based　flexible　electronics　with　robust　elasticity,　low　hysteresis,　and　excellent　durability　is　still　challenging.　Herein,　for　the　first　time,　B-N　coordination　was　employed　as　the　main　driving　force　to　promote　gelation　by　free　radical　polymerization　of　acrylamide　and　3-acrylamidophenylboronic　acid.　Owing　to　the　outstanding　stability　of　B-N　coordination,　the　hydrogels　could　retain　their　initial　stress　(＞95%)　during　500　tension　cycles　(strain　of　200%)　with　©　2022　The　Authors.　Published　by　American　Chemical　Society　and　Division　of　Chemical　Education,　Inc.
