DESCRIPTION:Well-defined molecular-recognition events can be used to direc
 t the assembly of macroscopic objects into larger aggregated structures. A
 crylamide-based gels functionalized with either host (cyclodextrin) rings 
 or small hydrocarbon-group guest moieties were synthesized. Pieces of host
  and guest gels are shown to adhere to one another through the mutual mole
 cular recognition of the host and the guest groups on their surfaces. In a
 ddition\, we have prepared supramolecular hydrogels by mixing host polymer
 s and guest polymers containing ferrocene. The hydrogel shows self-healing
  properties which can be controlled by redox stimuli.
