As a contracted porphyrin analogue, corrole shows more acidic and trinegative/triprotic nature compared with in the field of coordination chemistry. However, direct introduction into metal–organic framework is quite difficult due to its lower C2V symmetry. Herein, we report one-pot synthesis series porphyrin-based multivariate porphyrinic frameworks M1(TCPC)@M2-PCN-222 (M1 = CuIII, MnIII, FeIVCl; TCPC 5,10,15-tris(4-carboxyphenyl) corrole; M2 CoII, CuII, NiII, FeIIICl) applied them insertion Si–H bond α-diazoacetates. The resultant FeCl(TCPC)@Ni-PCN-222 displayed highest efficiency turnover number 796 based on amount Fe, which could be reused at least 5 times without negligible loss activity. Mechanistic studies disclosed that reactivity came from synergistic effect between FeCl(TCPC) Ni-PCN-222, acted as active site formation metal-carbene, whereas Ni-PCN-222 helped condense silane molecules for boosting bond.

All-inorganic lead-free halide perovskite Cs3Bi2I9 was encapsulated in a zirconium-porphyrin metal–organic framework (MOF-545) to create S-scheme heterojunction photocatalyst Cs3Bi2I9@MOF-545 for efficient copper-mediated photoinduced atom transfer radical polymerization (photo-ATRP). The close interfacial contact and the disparity work function between MOF-545 has been demonstrated facilitate charge at interface boost efficiency of photogenerated separation utilization. distinctive advantage enabled optimized effectively regulate Cu-mediated photo-ATRP diverse monomers under 850 nm near-infrared (NIR) light with good terminal fidelity, even achieving high monomer conversion on barriers 5 mm PP board 4 pigskin. In large reaction volume (250 mL), reached approximately 99% first-order kinetic behavior NIR light, demonstrating potential industrial applications. High photocatalytic activity maintained after 10 cycles use organic solvent (DMSO) or 6 days water immersion. Furthermore, it is unveiled that limited oxygen can enhance trithanolamine (TEOA) oxidation accelerate photocatalysts first time. This study offers insights into designing MOF-based augment performance NIR-light.
