Polar alcohol guest molecules regulate the stacking modes of 2-D MOF nanosheets

“…[11][12][13][14][15][16][17] Compared to traditional porous materials, the superior structural features of 2-D MOFs, such as high surface area, high porosity, high stability, adjustable pore size, and functionalized pore surface, make them benecial for the separation of important chemical raw materials, such as xylene isomers. [18][19][20][21][22][23] However, 2-D MOF nanosheets are too thin and easy to stack at random, which will block the pores that originally adsorb and separate gases, resulting in a reduced gas adsorption rate and separation efficiency. [24][25][26] Therefore, it is exceedingly essential and important to regulate the stacking modes of 2-D MOF nanosheets to improve the effect of gas adsorption and separation, which was largely neglected before.…”

Tailoring the Electrochemical Responses of MOF‐74 Via Dual‐Defect Engineering for Superior Energy Storage

“…[23][24][25] Modulators are often used to create structural defects in the MOF synthesis process, such as missing cluster or linker defects. [26,27] Monodentate modulators such as monocarboxylic acid (e.g., formic, [28] acetic, [29] benzoic acids, and derivatives [30,31] ) have been found to control crystal nucleation and growth by competing for coordination; while, alkaline modulators (e.g., ethylenediamine, [32] triethylamine [33,34] ) tailor crystal morphology or category via the protonation/deprotonation balance. In addition, inorganic acids (HCl, [35] HNO 3 /HF [36] ) have been found to accelerate the synthesis kinetics.…”

A Water‐Stable Cationic SIFSIX MOF for Luminescent Probing of Cr2O72− via Single‐Crystal to Single‐Crystal Transformation

“…Metal‐organic frameworks (MOFs) having high tunability [ 5–26 ] along with structural diversity [ 27–51 ] claim immense attention toward sensing due to their versatile superiority such as quick response time, high sensitivity and selectivity, operability, and recyclability. [ 40,52–53 ] However, cationic MOFs having distinct advantages over neutral MOFs received considerable attention for selective trapping of targeted anions as they can act as readily anion exchangeable hosts and provide room for the substitutable anions inside the charged and nanosized pores cavity.…”
