AI Article Synopsis
- A new type of non-planar 2D COF (Covalent Organic Framework) was created using a Z-shaped building block with a stair-stepped design.
- Compared to traditional planar COFs, this unique structure has a larger surface area and increased fluorescence.
- The non-planar COF showed promise for detecting explosives through a fluorescence quenching mechanism, highlighting its potential applications beyond conventional COF materials.
Article Abstract
Herein, a novel non-planar 2D COF with a stair-stepped structure was constructed from a Z-shaped building block for the first time. Compared with its similar planar COF, the unique stair-stepped non-planar COF possesses larger surface area and stronger fluorescence, which was further applied for specific explosive detection through a fluorescence quenching mechanism. This work not only extends the traditional planar 2D COF structures to unique non-planar structures based on the bottom-up design principle, but also expands the potential applications of COF materials.
