“…Photodegradation may be surprising at the first glance since Zr-based MOFs are often highlighted as materials with excellent photostabilities and stability against singlet oxygen which is generated during quenching of fluorescent and phosphorescent emitters. Numerous applications of PCN-224 which require efficient singlet oxygen production, such as photodynamic therapy, 34 photocatalytic degradation 64 or photodynamic sterilization 65 have been demonstrated. Photostability of PCN-224 MOF in liquid suspension was found to be excellent.…”

“…However, compared with the photocatalysts of PCN-224 and MOF-525 encapsulated perovskites with same CsPbI 3 percentage as PCN-222, CsPbI 3 @PCN-222(20%) has the best photocatalytic polymerization performance. The pore size of the MOFs, the distance between the porphyrins, and the positions of the host-guest band structure directly affect the singlet oxygen generation efficiency, [31] light absorption, the growth of perovskite in channels of MOFs, and the transport of photogenerated carriers of the hybrid photocatalyst. Therefore, the synergistic effect of MOF and perovskite is crucial to upgrade the catalytic activity of the photocatalyst in the PET-RAFT polymerization.…”

Stable binary nanohybrids based on all-inorganic halide perovskite encapsulated in porphyrinic Zr-MOF (PCN-222) are constructed for photoinduced electron transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization. The synergistic effect of perovskite and PCN-222 endows the photocatalyst with high-efficiency photogenic charge carrier separation and light absorption property. CsPbI 3 @PCN-222 (20%) is finally screened out as the oxygen and solvent-resistant photocatalyst for highly efficient photocontrolled polymerization of conjugated and unconjugated monomers under red to near infrared (NIR) light with high monomer conversion and narrow molecular weight distribution well-defined polymers (Đ < 1.20). Controllable polymers and ultrahigh molecular weight polymers (up to 1730000 g mol −1 ) are successfully obtained by chain extension and block copolymerization of various monomers. The constructed photocatalysts easily achieve excellent light and temporal control, and even show high MMA conversion with NIR light under a thick barrier.

“…The photocytotoxicity of four kinds of MOFs composed of Zr and TCPP, including cubic MOF‐525, rod‐shaped MOF‐545, spindle‐shaped PCN‐223, and spherical PCN‐224, toward Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ) was compared. [ 83 ] An cytotoxicity order of MOF‐545 > MOF‐525 > PCN‐224 > PCN‐223 was observed, indicating the remarkable effect of shape on cytotoxicity.…”

Reticular chemistry has become a powerful tool for scientists to design crystalline porous materials with different fundamental units. [1] Over the past decades, porous materials have gained great attention due to their outstanding performance and wide applications. Among various porous materials, the combination of metal nodes and organic linkers by coordination bonds creates new hybrid porous materials called metal-organic frameworks (MOFs) and opens a new window in the design of porous materials.Since the first report on MOFs by Yaghi's group in 1995, [2] more than 100 000 kinds of MOFs have been synthesized according to the Cambridge Structural Database (CSD). The unique characteristics, including tunable porosity, customized chemical composition, large specific surface area, and easy functionalization, make MOFs promising candidates for numerous applications in diverse fields such as gas storage and separation, catalysis, sensing, adsorption, energy, and biomedical sciences. [3] In addition, the large-scale production and commercialization of MOFs began from 2016. [4] For instance, the commercial MOF adsorbent for storage of 1-methylcyclopropene to ripen vegetables and fruits was driven to the market. [5] The Numat's ION-X gas cylinder was designed based on the MOF adsorbent to store hazardous gases for semiconductor industry, showing significant advantages over traditional adsorbents. [3a] Apart from the commercialization in gas storage, the MOF-303-based apparatus has been used to collect water in the desert. [6] Despite the advantages of MOFs, the wide application of MOFs has led to environmental health risks. The accidental release of MOF particles into the environment from their bulk-products is inevitable during the lifecycle of MOFs. The deposition, decomposition, and distribution of released MOFs in environmental media could result in the exposure to humans and other organisms, inducing various biological effects. In addition, the intentional administration of MOFs in biomedicine (such as bioimaging, drug delivery system) also leads to the exposure risks to humans. Under these circumstances, the environmental health risks of MOFs are unavoidable.The toxicity of MOFs plays an important role in their health risk assessment. Compared with in vivo and ex vivo toxicity assessments, in vitro toxicity evaluation based on cell culture is low cost, fast, and high throughput, making it an ideal model in toxicity research. As the basic unit in organism, cells play an important role in life activity. The toxic effects on cells would affect their function and therefore induce significant response
