The formation of imine bond is reversible. This feature has been taken advantage of by chemists for accomplishing high yielding self‐assembly. On the other hand, it also jeopardizes the intrinsic stability of these self‐assembled products. However, some recent discoveries demonstrate that some of these imine bond containing molecules could be rather stable or kinetically inert. A deep investigation indicated that such enhanced stability results from, at least partially, multivalence. Such results also inspire chemists to use imine condensation for self‐assembly in water, a solvent that is considered not compatible with imine bond for a long time.
