COF-5共价有机骨架材料|Covalent Organic Frameworks 共价有机框架(Covalent Organic Frameworks)具备密度低、比表面积大、热稳定性好的优点引起我们的关注,仅由轻元素构成的COF-5易与气体分子发生相互作用,且其…
Covalent organic frameworks (COFs) are a class of crystalline porous polymer that allows the atomically precise integration of organic units into extended structures with periodic skeletons and ordered nanopores. One important feature of COFs is that they are designable; that is, the geometry and ...
reconstructed covalent organic frameworks重建共价有机框架(Reconstructed Covalent Organic Frameworks) 1. 简介 共价有机框架(Covalent Organic Frameworks,简称COFs)是一类由有机分子通过共价键连接而成的多孔晶体材料。COFs具有高度可调性、大孔隙表面积和可控的孔径尺寸等特点,因此在气体吸附、催化反应、分离技术等领域...
共价有机框架(Covalent Organic Frameworks, COFs)材料是一种新型的、共价键合的纯有机多孔晶型材料,被称为“有机分子筛"。结晶问题是多孔共价有机骨架(COF)化学中的突出问题,它们的结构表征仅限于粉末X射线或电子衍射数据的建模和解决方案,尚未报道适合于X射线衍射表征的COF单晶。
COFs orcovalent organic frameworksare a new form of crystalline porous materials composed of “light” atoms, e.g., B, N, C, O, etc. Due to their highly organized structures connected by strong covalent bonds, COF materials have several advantages, including uniform porosity, large specific su...
