Fig. 2: Cartoon illustration of the initiator arrays that lead to proximity-induced accelerated polymerizations.

a Nanoscale UiO-66, as a representative MOF material, presents the surface-exposed active metal center (Zr6) array. The structure and distribution of these catalytically active clusters are determined by the crystal lattice. b Proposed working cycle of MOF-aided accelerated preparation of free polypeptides and MOF@polypeptide hybrid materials.
