By virtue of visible light absorption ability, energy band structure and electronic affinity of covalent organic frameworks (COFs) can be easily tuned at the molecular level, making them as attractive...
The construction of three-dimensional (3D) covalent organic frameworks (COFs), especially full-conjugated 3D COFs is a long-standing challenge. Herein, we report a saddle-like, π-conjugated cyclooctatetrathiophene (COTh) as a tetrahedral node to...
Herein, a novel 2D nonplanar COF with 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 nonplanar...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
