Organic Photothermal Cocrystals: Rational Design, Controlled Synthesis, and Advanced Application

Advanced Science, Год журнала: 2023, Номер 10(11)

Опубликована: Янв. 27, 2023

Abstract Organic photothermal cocrystals, integrating the advantages of intrinsic organic cocrystals and fascinating conversion ability, hold attracted considerable interest in both basic science practical applications, involving photoacoustic imaging, seawater desalination, therapy, so on. However, these currently suffer individual cases discovered step by step, as well deep systemic investigation corresponding mechanisms is rarely carried out, suggesting a huge challenge for their further developments. Therefore, it urgently necessary to investigate explore rational design synthesis high‐performance future applications. This review first systematically summarizes cocrystal terms molecular classification, mechanism, The timely interpretation effect will provide broad prospects purposeful fabrication excellent toward great efficiency, low cost, multifunctionality.

Three new POM-based compounds, with formulae [Na0.63Ag3(Htba)2.37(tba)0.63(H2O)2(PMo12O40)]·4H2O (Ag3PMo), [Ag4(Htba)4(H2O)2(PMo12O40)](NO3)·H2O (Ag4PMo), and [Ag3(Htba)2(tba)(PW12O40)0.5](NO3)0.5·13H2O (Ag3PW), were prepared a 3-(4H-1,2,4-triazol-4-yl)benzoic acid (Htba) ligand, Keggin-type anions ([PMo12O40]3–/[PW12O40]3–), silver ion (Ag+). The structural features of these compounds are particularly different from the multinuclear subunits, which [Ag3(tba)3] clusters in Ag3PMo, [Ag4(tba)3] chains Ag4PMo, [Ag3(tba)3]2 Ag3PW, connected by multidonor atom tba ligands Ag+ ions. Meanwhile, polyanions act as polydentate to link adjacent Ag-tba metal–organic units expand their spatial dimensions. These heterogeneous catalysts, exhibit high stability excellent catalytic activity construct benzimidazoles. Ag3PMo could efficiently catalyze condensation benzene-1,2-diamines benzaldehydes produce benzimidazoles good yields. In addition, be reused up 7 times was suitable for gram-scale reactions.

Molybdenum (VI)‐oxo Clusters Incorporation Activates g‐C₃N₄ with Simultaneously Regulating Charge Transfer and Reaction Centers for Boosting Photocatalytic Performance

Advanced Functional Materials, Год журнала: 2022, Номер 32(38)

Опубликована: Июль 7, 2022

Abstract Establishing local built‐in electric field of 2D semiconductors is one the promising strategies to regulate oriented charge delivery active centers for enhancing photocatalytic performance. Herein, a novel heptamolybdate polyanions‐intercalated porous g‐C 3 N 4 ([Mo 7 O 24 ] 6− ‐ p CN) catalyst with integrating highly desirable visible‐light features reported. After intercalation, apparent reaction rate constants ( k app ) [Mo CN bisphenol A (BPA) and 4‐chlorophenol (4‐CP) photodegradation are remarkably enhanced, which 9.0 6.4 times faster than those CN, respectively. Analogously, values 6– ‐CN BPA 4‐CP removal also improved by contrast CN. The experimental results density functional theory calculations indicate that formed in polarization direction from aromatic rings inserted clusters. Driven field, photogenerated carriers can be efficiently separated better reactive oxidative species (ROSs) production. These atoms proved as adsorption sites phenols, greatly reducing migration distance ROSs thus improving performances. This work offers reliable strategy construct via polyoxometalates intercalation effective solar energy conversion phenolic wastewater remediation.

Synthetic framework materials have been cherished as appealing candidates for separation membranes in daily life and industry, while the challenges still remain precise control of aperture distribution threshold, mild processing methods, extensive application aspects. Here, we show a two-dimensional (2D) processible supramolecular (SF) by integrating directional organic host-guest motifs inorganic functional polyanionic clusters. The thickness flexibility obtained 2D SFs are tuned solvent modulation to interlayer interactions, optimized with limited layers but micron-sized areas used fabricate sustainable membranes. uniform nanopores allow membrane composed layered SF exhibit strict size retention substrates rejection value 3.8 nm, accuracy within 5 kDa proteins. Furthermore, performs high charge selectivity charged organics, nanoparticles, proteins, due insertion clusters skeletons.

Tuning the Chirality Evolution in Achiral Subnanometer Systems by Judicious Control of Molecule Interactions

Journal of the American Chemical Society, Год журнала: 2024, Номер 146(18), С. 12819 - 12827

Опубликована: Апрель 26, 2024

Chirality evolution from molecule levels to the nanoscale in an achiral system is a fundamental issue that remains undiscovered. Here, we report assembly of polyoxometalate (POM) clusters into chiral subnanostructures systems by programmable single-molecule interactions. Driven competing binding Ca2+ and surface ligands, POM assemblies would twist helical nanobelts, nanorings, nanotubes with tunable helicity. Chiral molecules can be used differentiate formation energies isomers immobilize homochiral isomer, where strong circular dichroism (CD) signals are obtained both solutions films. nanobelts as circularly polarized light (CPL) photodetectors due their distinct chiroptic responsivity for right left CPL. By fine-tuning interactions at levels, morphology CD spectra precisely controlled, providing atomic precision model investigation structure–chirality relationship chirality manipulation nanoscale.
