In the current paper, we successfully developed and used metal-organic frameworks (MOFs) based on MIL-101(Cr)-NH with phosphorus acid functional groups MIL-101(Cr)-N(CHPOH). The synthesized metal-organic frameworks (MOFs) as a multi-functional heterogeneous and nanoporous catalyst were used for the synthesis of -amino-2-pyridone and pyrano [2,3-]pyrazole derivatives via reaction of ethyl cyanoacetate or ethyl acetoacetate, hydrazine hydrate, malononitrile, and various aldehydes. The final step of the reaction mechanism was preceded by a cooperative vinylogous anomeric-based oxidation. Recycle and reusability of the described catalyst MIL-101(Cr)-N(CHPOH) were also investigated.

During the oxygen evolution reaction (OER), metal-organic framework (MOF) catalysts undergo structural reorganization, a phenomenon that is still not fully comprehended. Additionally, designing MOFs that undergo structural reconstruction to produce highly active OER catalysts continues to pose significant challenges. Herein, a bimetallic MOF (CoNi-MOF) with carboxylate oxygen and pyridine nitrogen coordination has been synthesized and its reconstruction behavior has been analyzed.

Specific tumor-targeted gene delivery remains an unsolved therapeutic issue due to aberrant vascularization in tumor microenvironment (TME). Some bacteria exhibit spontaneous chemotaxis toward the anaerobic and immune-suppressive TME, which makes them ideal natural vehicles for cancer gene therapy. Here, we conjugated ZIF-8 metal-organic frameworks encapsulating eukaryotic murine interleukin 2 () expression plasmid onto the surface of VNP20009, an attenuated strain with well-documented anti-cancer activity, and constructed a TME-targeted delivery system named /ZIF-8@.

The physical separation of CH from CO on metal-organic frameworks (MOFs) has received a substantial amount of research interest due to its advantages of simplicity, security, and energy efficiency. However, the exploitation of ideal MOF adsorbents for CH/CO separation remains a challenging task due to their similar physical properties and molecular sizes. Herein, we report a unique CH nano-trap constructed using accessible oxygen and nitrogen sites, which exhibits energetic favorability toward CH molecules.

Thiazolo[5,4-d]thiazole-2,5-dicarboxylic acid (HThz), a thiazolothiazole (TTz) derivative with carboxylic acid groups, was synthesized as a ligand for the creation of five MOFs, each associated with distinct metal ions including Ag, Mn, Co, Zn, and Cu. The cathodic electrochemiluminescence (ECL) of HThz and the resulting MOFs was investigated. HThz was found to generate ECL signals, but this process was heavily reliant on potassium persulfate (KSO) as a co-reactant.

Physisorption presents a promising alternative to cryogenic distillation for capturing the most potent greenhouse gas, SF, but existing adsorbents face challenges in meeting diverse chemical and engineering concerns. Herein, with insights into in-pore chemistry and industrial process design, we report a systematic investigation that constructed two low-cost composites pellets (Al(fum)@2%HPC and Al(fum)@5%Kaolin) coupled with an innovative two-stage Vacuum Temperature Swing Adsorption (VTSA) process for the ultra-efficient recovery of low-concentration SF from N.
