Aug 22, 2022 · One-dimensional (1D) covalent polymers that are packed into a framework structure can be viewed as a 1D covalent org. framework (COF), but making a single crystal of this has been elusive. Herein, by combining labile metal coordination and dynamic covalent chem., we discover a strategy to synthesize single-crystal metallo-COFs under ...

Mar 18, 2020 · Here, the authors demonstrate a strategy to synthesize single crystalline 1D metallo-covalent organic frameworks by combining dynamic covalent chemistry and metal-ligand coordination.

Feb 1, 2024 · The topological diversity of covalent organic frameworks (COFs) enables considerable space for exploring their structure-performance relationships. In this study, we report a sequence of novel 1D COFs (EO, ES, and ESe-COF) with typical 4-c sql topology that can be interconnected with VIA group elements (O, S, and Se) via a modular design strategy.

Oct 30, 2024 · Imide-linked 1D COF with nickel phthalocyanine building blocks exhibits superior electrocatalytic performance for NO 3 RR with nitrate-to-NH 3 Faradaic efficiency of 100%, NH 3 current density of −246 mA/cm 2, and NH 3 yield rate of 19.5 mg cm −2 h −1.

Dec 24, 2020 · Here, we develop a new COF made up of 1,3,6,8-tetrakis(p-formylphenyl)pyrene (TFPPy) and 4,4′-diaminobenzophenone (DABP) that exhibits a rare one-dimensional (1D) structure. The resulting frameworks possess good crystallinity, comparatively high Brunauer–Emmett–Teller (BET) surface area (426 m 2 /g), and good thermal stability (360 °C).

Apr 17, 2024 · Herein, a novel crystalline 1D-COF (FZU-66) was constructed and further decorated with cobalt(II), which led to excellent heterogeneous catalytic performance in the C–H bond oxidation of ethylbenzene.

Feb 6, 2025 · We present a simple and rapid synthetic method leveraging coordination-directed imine formation to construct families of highly crystalline porous materials, referred to as MOF-COF (MOCOF) hybrid frameworks. 14 MOCOF single crystals were obtained within 1 to 2 days, with sizes ranging from 50 to 500 μm.

May 22, 2024 · Herein we report exterior functionalization of a one-dimensional (1D) COF by introducing terpyridine units on its edges to anchor Pt (II) cations. The as-obtained 1D COF (Pt-Tpy-COF) exhibits high photocatalytic activity for hydrogen evolution from water, with a hydrogen evolution rate up to 7.8 mmol g −1 h −1.

Jan 1, 2023 · A novel bis(triphenylamine)-based 1D TAPD-TDA COF was successfully constructed. 1D COF displays comparatively high porosity, good thermal and chemical stability. The uniform 1D COF film exhibits remarkable NIR EC performance.

May 8, 2024 · We designed a new metalated 1D COF based on nonlinear building units by incorporating Co atoms into PAD-COF via post-synthetic modification. The marginal exposure sites and visible-light absorption range obtained by Co SAS/PAD-COF increased.
