Controlling the formation and directional growth of hydrogels is a challenge. In this paper, a new methodology to program the gel formation both over space and time is proposed, using the diffusion and subsequent hydrolysis of 1,1′‐carbonyldiimidazole from an immiscible organic solution to the aqueous gel media.
