2025年1月2日 · Here, we show COFs with 2.5-dimensional (2.5D) skeletons, which are microscopically constructed with 3D bonds but have macroscopically 2D planar shapes.

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.

2021年6月1日 · Covalent organic frameworks (COFs) are the emerging type of organic crystalline porous materials, prepared through reticular chemistry with building blocks featuring light elements (such as C, H, O, N, or B atoms), and connected through the covalent bond and extended into two or three dimensions.

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.
