Chemo‐Enzymatic Route for Covalent Cellulose Fiber Dyeing

Chemistry – A European Journal, Volume 32, Issue 14, 15 April 2026.
This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...

Preparation of Microporous Organic Polymers and Their Properties of Gas Adsorption [PDF]

, 2016
微孔有机聚合物拥有较多尺寸小于2nm的微孔结构，具有较高的比表面积、大的孔体积、低的骨架密度、高的化学稳定性等优势，因此在气体吸附与存储、催化等领域具有潜在的应用价值。近十年来，微孔有机聚合物得到了快速的发展。微孔有机聚合物依据其结构不同可分为：超交联微孔聚合物（HCPs）、共轭微孔聚合物（CMPs）、共价有机骨架（COFs）和固有微孔聚合物（PIMs）。目前，面临的主要难题是部分微孔有机聚合物的合成需要用到过渡金属或贵重金属催化剂，昂贵的单体，无法大规模生产。因此，本论文中 ...

Thiophosphate-Based Covalent Organic Framework (COF) or Porous Organic Polymer (POP)?

Macromol
There are few examples of covalent organic frameworks (COFs) based on phosphorus as the building element, probably because the structure of most phosphorus derivatives is pyramidal, which may prevent the stacking expected for classical 2-dimensional COFs.
