Strategies in Metal–Organic Framework‐based Catalysts for the Aerobic Oxidation of Alcohols and Recent Progress

Abstract

Metal–organic frameworks (MOFs), which are porous inorganic–organic hybrid materials, act as versatile catalyst platforms for various organic transformations. In particular, the aerobic oxidation of alcohols to the corresponding aldehydes (or ketones) has been extensively studied using various MOFs and their analogs. In this account, we summarize the performance of MOF‐based catalysts for the aerobic oxidation of alcohols based on the position of the catalytic species and the type of functionalization. Moreover, recent advances in MOF‐based catalysts for aerobic oxidation are discussed in terms of catalytic efficiency and substrate size discrimination.

Structural properties of [Cu(ii)3L6] cages: bridged polyatomic anion effects on unprecedented efficiency of heterogeneous catechol oxidation

“…Current trends in research on desirable metal-organic coordination species have prioritized efficient applications. [1][2][3][4][5][6][7][8][9][10][11][12] Among the various relevant factors therein, counteranions play significant roles in both the process of topology formation and the functions of various coordination systems such as catenanes, rotaxanes, macrocycles, cages, and infinite networks. [13][14][15] In particular, a momentous challenge for comprehensive molecular cage systems that include anions is to discover task-specific functions such as recognition, adsorption/desorption, molecular containers, ion exchangers, chemo-sensors, proton conductivity, drug delivery, and catalysis.…”

Advances in 2D coordination networks for single‐crystal‐to‐single‐crystal applications beyond confined pores

“…Synthesis and packing array of molecular-level 2D networks is, in these days, a substantial hot issue, due to task-specific practical applications to gas adsorption/desorption, recognition, separation, molecular containers, energy transfer template, chemo-sensors, ion exchangers, drying agents, biomimics systems, nuclear waste storage, and heterogeneous catalysis. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] An important conceptual characteristic of such 2D frameworks is a possibility of guest-induced stretching and sliding between layer and layer via tuning of weak interactions such as van der Waals interactions, iondipole forces, hydrogen bondings, and dipole-dipole attractions. [15][16][17][18][19][20] For 2D networks, the interlayer sliding and stretching phenomena are strongly depending on the hydrophilicity, coordinating ability, protic properties, polarity, and bulkiness of adsorbed guest molecules.…”

Binding Materials for MOF Monolith Shaping Processes: A Review towards Real Life Application

“…MOFs are typically characterized by high porosity, low density, and excellent biocompatibility [4]. These properties render them excellent candidates for applications related to sorption, catalysis, chromatography, energy storage, sensors, drug delivery, and nonlinear optics [5][6][7]. Recently, apart from an in-lab investigation, MOFs have been examined for industrial applications as well.…”
