2024年6月5日 · Covalent organic frameworks (COFs) are a functional material class able to harness, convert and store energy. However, after almost 20 years of research, there are no coherent prediction rules for...

6 天之前 · Figure 2c shows sequential DFM images depicting the crystal growth trajectory of COF-300. Initially, the longitudinal length of single-crystal COF-300 is approximately 1.61 μm (Fig. 2c : t-t 0 = 0).

2024年12月12日 · Here, we present real-space imaging of an extensively studied two-dimensional imine-based COF. Contrary to the conventional understanding that this COF features uniform hexagonal pores, our observations reveal the presence of two distinct sets of pores with differences in shape and size.

2023年8月15日 · Here, we synthesize two 3D crystalline COF films. The frameworks, the ionic B-based and neutral C-based COFs, have similar unit cell parameters, which enables their epitaxial stacking in a layered 3D COF film. The film growth was monitored in real time using a quartz crystal microbalance, showing linear growth with respect to reaction time.

2020年1月30日 · Herein, we report a simple and scalable way to grow large-area, pliable, free-standing COF membranes via a one-step route at organic–organic interface. The pore sizes of the membranes can be...

2D covalent organic frameworks (COFs) are highly porous crystalline materials with promising applications in organic electronics. Current methods involve either on-surface synthesis (solid surface) or interfacial synthesis (liquid/liquid, liquid/gas interface) to create thin films for these applications, each with its drawbacks.

The new porous material for capturing carbon dioxide, called a covalent organic framework (COF), has hexagonal channels decorated with polyamines that efficiently bind CO 2 molecules (blue and ...

2024年7月16日 · Prediction of experimental specific surface area of COFs based on structural images. The proposed COFNet model integrates deep learning algorithms with attention mechanism. The COFNet model innovatively accepts COF structural images and derived statistical features as hybrid inputs.

2020年1月22日 · Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with permanent porosity and highly ordered structures. Unlike other polymers, a significant feature of COFs is that they are structurally predesignable, synthetically controllable, and functionally manageable.

3 天之前 · Herein, we designed and prepared three-dimensional (3D) hierarchical porous ORR catalysts (CuFe-NHPC/CNFs) enriched with CuFe alloys and Cu/Fe-N x sites via a COF/MOF hybridization strategy, which have a half-wave potential of 0.88 V. In detail, the strategy includes electrospinning, two-step impregnation growth of COF/MOF hybrids, and …
