“…Theo hiểu biết của chúng tôi, bằng việc sử dụng phương pháp nhiệt dung môi với các tiền chất, dung môi hoặc chất thêm khác nhau và tỷ lệ mol các chất tham gia phản ứng khác nhau, thời gian và nhiệt độ kết tinh khác nhau hay quá trình xử lý sau kết tinh khác nhau, mà kết quả bề mặt riêng theo BET của ZIF-90 được báo cáo trong khoảng hơn 40 công trình dao động từ 46 m 2 /g [10] đến 1.664 m 2 /g [26]. Trong đó, BET xác định được dưới 1.000 m 2 /g [6,10,27,31,32,35,36,40,41,55,58,62,71,72], trong khoảng 1.000-1.300 m 2 /g [5][6][7]11,18,37,[42][43][44][45]47,49,50,53,56,[68][69][70]73] và trên 1.300 m 2 /g [9,24,26,57,66,74]. Như vậy, kể từ 2008 đến nay, BET của ZIF-90 được tổng hợp thành công có giá trị cao nhất bằng 1.664 m 2 /g [26].…”

The thoroughly studied zeolitic framework is ZIF-90 which consist of Zn2+ centers linked by imidazolate-2-carboxyaldehyde. In this compound, the large spherical pores with 11.2 Å diameter are interconnected via much narrower 6-ring windows with 3.5 Å diameter, thermal and chemical stability, so it has been interested by many research groups in synthesis, characterization and application. However, studies on ZIF-90 are still limited, mainly simulation studies and laboratory studies.This article overviews the situation of synthesis, characterization and application of ZIF-90 since its discovery in 2008 to present, and proposes issues that need attention in the future so that ZIF-90 can be synthesized high efficiency and good application in practice.

The exacerbation of environmental issues is increasingly attributed to the anthropogenic emissions of carbon dioxide (CO2) . CO2 is a cost‐effective and readily available C1 source. The conversion of CO2 into value‐added organic chemicals, such as cyclic carbonate and 2‐oxazolidinone, through carboxylation cyclization reactions shows promise in reducing carbon emissions and combating climate change. The use of catalysts can facilitate this process, with heterogeneous catalysts emerging as favorable due to their advantages of easy recovery and structural stability. This paper provides a comprehensive review of heterogeneous catalysts that have been utilized for the carboxylation cyclization of CO2 to afford cyclic carbonates and oxazolidinones in recent years. The catalysts include metal organic frameworks, covalent organic frameworks, super‐crosslinked polymers, conjugated microporous polymers, porous ionic organic polymers, and composite materials. We give a detailed synthesis route for each type of catalysts. Furthermore, the characteristics of the catalysts, such as BET specific surface area, CO2 adsorption capacity, and catalytic performance, is summarized and analyzed to offer insights for improving heterogeneous catalysts for CO2 conversion via carboxylation cyclization reactions in future research.

Post Synthetic Modification (PSM) of Metal‐Organic Frameworks (MOFs) is a crucial strategy for developing new MOFs with enhanced functional properties compared to their parent one. PSM can be accomplished through various methods:1) modification of organic linkers; 2) exchange of metal ions or nodes; and 3) inclusion or exchange of solvent/guest molecules. Herein, PSM of bimetallic and monometallic MOFs containing biphenyl dinitro‐tetra‐carboxylates (NCA) are demonstrated. The tetra carboxylate NCA, produces monometallic Cd‐MOF‐1 and Cu‐MOF‐1 and bimetallic CoZn‐MOF in solvothermal reactions with the corresponding metal salts. The CoZn‐MOF undergoes post‐synthetic transmetallation with Cd(NO3)2 and Cu(NO3)2 in aqueous solution to yield Cd‐MOF‐2 and Cu‐MOF‐2, respectively. Additionally, green crystals of Cu‐MOF‐1 found to undergo a single‐crystal‐to‐single‐crystal (SCSC) transformation to blue crystals of Cu‐MOF‐3 upon dipped into water at room temperature. These MOFs demonstrate notable proton conductivities ranging from 10‐3 to 10‐4 S cm‐1 under variable temperatures and humidity levels. Among them, Cu‐MOF‐3 achieves the highest proton conductivity of 1.36 × 10‐3 S cm‐1 at 90 °C and 98% relative humidity, attributed to its continuous and extensive hydrogen bonding network, which provides effective proton conduction pathways within the MOF. This work highlights a convenient strategy for designing proton‐conducting MOFs via post‐synthetic modification.
