Article Abstract
Sequential assembly of donor-acceptor components at the molecular level within a MOF is an effective strategy to achieve efficient electron-hole separation for enhancing the activity of photocatalysts. Meanwhile, the highly efficient and selective functionalization of tetrahydroisoquinoline (THIQ) under mild conditions remains an urgent demand in both the scientific and industrial communities. This work reports a donor-acceptor MOF photocatalyst () constructed by the coordinated assembly of donor and acceptor components, in which a naphthalene unit serves as an electron donor and a perylenediimide unit as an electron acceptor. The can undergo rapid photoinduced electron transfer and exhibits long-lived charge-separated states with prominent photochromism. The photogenerated charges can rapidly activate the substrates THIQ and O, thereby achieving a highly selective coupling reaction of the C-C and C-P bonds of THIQ. In addition to the gram-scale reaction, can also be applied to conduct photocatalytic reactions under natural sunlight and ambient air, highlighting its prospects for industrial application.

Development of novel photocatalysts for hydrogen peroxide (HO) production from water and oxygen is gathering great attention, but still suffers from inefficient photogenerated charge mobility. Reticular chemistry in metal-organic frameworks (MOFs) provides a promising platform to enhance the charge-transfer kinetics by assembling a donor-acceptor (D-A) system. Here, we designed and synthesized a series of D-A type MOFs (UiO-67-NB, UiO-67-PE/BB, and UiO-67-PE/NB) via regulating the interaction mode of donor and acceptor.

Through-space charge transfer (TSCT) thermally activated delayed fluorescence (TADF) materials have recently shown great potential for applications in X-ray detection and imaging due to their efficient triplet exciton utilization. By rational tuning of molecular/electronic structures of D and A moieties and precise regulation of TSCT interactions, tunable emission and TSCT-based TADF can be achieved. However, the TSCT interactions in organic D-A systems are somewhat difficult to design and control precisely resulting from relatively weak D-A supramolecular interactions.

The persistent presence of tetracycline antibiotics such as chlortetracycline (CTC) and oxytetracycline (OTC) in aquatic environments has emerged as a critical environmental concern. To address this challenge, we developed a novel composite adsorbent through strategic doping of bismuth into the HKUST-1 metal-organic framework (MOF), followed by encapsulation within a copper alginate (SA-Cu) hydrogel matrix. This innovative synthesis protocol yielded BiHKUST-1/SA-Cu, which was characterized using SEM, XRD, FT-IR, and XPS to elucidate its structural and chemical properties.

Porphyrin-based metal-organic frameworks (MOFs) offer a unique platform for building porous donor-acceptor networks that exhibit long-lived charge separation and transport upon incorporation of electron acceptor guest species. Here, porphyrin-based MOFs, PCN-222-(H) and PCN-222-(Zn), synthesized as nanoparticle suspensions, are successfully infiltrated with fullerene acceptor molecules, C or PCBM, in both polar and nonpolar solvent environments. The location and relative binding strength of these guest species are evaluated through a combination of N physisorption measurements, photoluminescence quenching, and UV-vis absorption titration experiments.
