Supramolecular assemblies have gained tremendous attention due to their apparent ability to catalyze reactions with the efficiencies of natural enzymes. Using Born-Oppenheimer molecular dynamics and density functional theory, we identify the origin of the catalytic power of the supramolecular assembly Ga4L6 12− on the reductive elimination reaction from gold complexes.By comparing the catalyzed and uncatalyzed reaction in explicit solvent to identify the reaction free energies of the reactants, transition states, and products, we determine that the catalysis arises from an encapsulation of a catalytic moiety-a primary water moleculethat is unlike the biomimetic scenario of catalysis through direct host-guest interactions.

“…The integration of eROP and enzyme mediated ATRP was a promising environmentally benign process for the preparation of biomaterials. Tang et al later reported the polymerization PEGMA using DhHP-6@ZIF-8 (DhHP-6@ZIF-8 = DhHP-6 embedded in zeolite imidazolate framework-8) as a catalyst and BPN as an initiator [ 139 ]. This catalyst could be applied to the polymerization of PEGA and NIPAAm.…”

Atom transfer radical polymerization (ATRP) is one of the most successful techniques for the preparation of well-defined polymers with controllable molecular weights, narrow molecular weight distributions, specific macromolecular architectures, and precisely designed functionalities. ATRP usually involves transition-metal complex as catalyst. As the most commonly used copper complex catalyst is usually biologically toxic and environmentally unsafe, considerable interest has been focused on iron complex, enzyme, and metal-free catalysts owing to their low toxicity, inexpensive cost, commercial availability and environmental friendliness. This review aims to provide a comprehensive understanding of iron catalyst used in normal, reverse, AGET, ICAR, GAMA, and SARA ATRP, enzyme as well as metal-free catalyst mediated ATRP in the point of view of catalytic activity, initiation efficiency, and polymerization controllability. The principle of ATRP and the development of iron ligand are briefly discussed. The recent development of enzyme-mediated ATRP, the latest research progress on metal-free ATRP, and the application of metal-free ATRP in interdisciplinary areas are highlighted in sections. The prospects and challenges of these three ATRP techniques are also described in the review.

“…The embedded or encapsulated DhHP‐6 with the enzyme mimicking ability could boost the activity of the enzyme. The entrapment of DhHP‐6 within the porous shield of ZIF‐8 was confirmed by FT‐IR and PXRD, thus solidfying the strong structural integrity of ZIF‐8 framework which was capable of accomplishing self‐assembly even in the absence of covalent bonding for biomimetic mineralization …”

Nanoarchitectonics of Biofunctionalized Metal–Organic Frameworks with Biological Macromolecules and Living Cells

The formation of biofunctionalized metal–organic frameworks (MOFs) by growing them on a variety of macromolecular biological species, particularly on enzymes and living cells, offers exciting opportunities for a wide range of applications, including biocatalysis, biosensing, and diagnoses. MOFs are commonly subjected to biofunctionalization and biomimetic mineralization, owing to their good chemical and thermal stabilities and easy preparation in aqueous medium under ambient conditions. The functionalization of MOFs with biological substances, such as enzymes, nonenzymatic proteins, and living cells promotes the formation of MOF‐based biocomposites which retain the biological functions of the embedded biological substances. The most common method to construct these biofunctionalized MOFs is either by directly growing the MOF on the biological moiety or by postsynthetic modification of the exterior surface of the MOF with the desired biological species. In particular, hierarchically porous MOFs (containing both mesopores and micropores) are ideal candidates for hosting enzymes and for the translocation of nonenzymatic proteins. This review covers various advanced strategies for developing MOF‐based biocomposites for a wide range of bioapplications, such as biomedical storage, tumor cell targeting, and drug delivery. The influence of MOFs on the biological activity of living cells and future prospects for developing novel MOF‐based biorefinery are discussed.
