swollen segments (Figure 5C) and application of toluene to the
interface (Figure 5D) promotes fast self-healing, reforming the
full gel in only a few minutes (Figure 5E). Self-healing is even
faster when immersing the blocks in solvent, with healing occur-
ring in less than 1 min. Note that oscillating rheology was not
feasible due to the slow degradation of the broken network in air.
While the gels are stable under inert conditions for long periods,
slow hydrolysis is observed over 1 week when stored in air.

measurements.

We report the development of the first polymeric frustrated
Lewis pairs. These poly(FLP)s offer an entirely new type of dy-
namic crosslinks, allowing for triggered gelation, responsive gel
rupture and self-healing. The gels can be tuned by controlling
loading of the boron and phosphorus functional monomers, intro-
duced into styrene copolymers through controlled radical
polymerization. This initial finding offers a new concept in mate-
rials design through altering the macromolecular architecture
