Recent trends in covalent organic frameworks (COFs) for carbon dioxide reduction

Abstract

As the ultimate carbon emission of the combustion process, carbon dioxide (CO2) is a serious environmental threat in increasing the global climate temperature through the greenhouse effect. Porous heterogeneous catalysts...

Multifunctionality of luminescent molecular nanomagnets based on lanthanide complexes

“…[26][27][28] The generation of targeted physical functionalities in molecule-based materials can be realized using the molecular building block approach where molecular components (metal ions, organic/inorganic molecules, ligands, or radicals) of the specific intrinsic properties are combined via covalent or coordination bonds as well as supramolecular interactions. [29][30][31] They are usually synthesized under soft laboratory conditions leading to the crystalline form, enabling their structural characterization. Owing to these advantages, molecule-based materials, which range from discrete molecules and supramolecular systems to coordination polymers (CPs) and metal-organic frameworks (MOFs), have been used widely as a source of multifunctionality, providing the unique groups of luminescent ferroelectric materials, 32,33 NLO-active magnets, 34,35 multiferroics, 36,37 and photoswitchable porous, ion-conductive or magnetic systems, [38][39][40][41] among others.…”

A BODIPY‐Based 1D Covalent Organic Framework for Photocatalytic Aerobic Oxidation

“…[17] Photoactive COFs are regarded as an efficient, and environmentally-friendly photocatalyst for environment remediation and energy conservation, because they are able to utilize solar energy to degradation of pollutants, [18] split water to generate H 2 and O 2 [19,20] and convert greenhouse gas CO 2 to high value chemicals. [21] Although COFs as photocatalysts have been studied for several years, the organic transformations photocatalyzed by COFs under mild conditions is remain rarely explored. [22,23] One-dimensional (1D) COFs, which are constructed from 1D confined covalent linkages with non-covalent interactions (such as π-π interactions, hydrogen bonding, etc.)…”

“…Covalent organic frameworks (COFs) as a class of materials with permanent porosity, highly ordered structures and high surface areas have widespread applications, such as gas storage/separation, chemical sensing and heterogeneous catalysis [17] . Photoactive COFs are regarded as an efficient, and environmentally‐friendly photocatalyst for environment remediation and energy conservation, because they are able to utilize solar energy to degradation of pollutants, [18] split water to generate H 2 and O 2 [19,20] and convert greenhouse gas CO 2 to high value chemicals [21] .

Rhenium(I) Complex-Containing Amphiphilic Metallopolymer Stabilizing CdS Quantum Dots for Synergistically Boosting Photoreduction of CO2

“…Among these components, the PS and Cat play critical roles in determining photocatalytic efficiency. 3 Photocatalytic CO 2 reduction has been extensively studied with a range of materials, including semiconductor quantum dots, 4,5 metal-oxide semiconductors, 6 graphene and its derivatives, 7,8 graphitic carbon nitride (g-C 3 N 4 ), 9,10 framework materials, 11,12 and transition metal complexes 13,14 as well as their composites. 15,16 Among these materials, semiconducting CdS quantum dots (QDs) have emerged as highly effective catalysts for light-driven CO 2 reduction due to their unique properties, which allow simple modulation of energy band gaps by varying dot sizes, compositions, and capping agents.…”
