Covalent organic frameworks (COFs) incorporating oligo(phenylenevinylene) units have shown promise in enhancing photocatalytic hydrogen evolution. This study presents a series of linear oligo(phenylenevinylene)-based COFs with various ratios of β-ketoenamine to imine linkages. The COFs-950-OMe are crystalline, exhibiting higher surface area compared to amorphous COFs-950, due to the introduction of methoxy side groups.
包含亚苯基乙烯基低聚物单元的共价有机框架（COFs）在增强光催化析氢方面已显示出前景。本研究展示了一系列具有不同β-酮烯胺与亚胺键比例的基于亚苯基乙烯基低聚物的线性COFs。由于甲氧基侧基的引入，COFs-950-OMe是结晶性的，与非晶态的COFs-950相比具有更高的表面积。
