Construction of quinoline-4-carboxylic ester linked covalent organic framework via Doebner–von Miller reaction The irreversible locking of reversible imine linkages in COFs into quinoline-4-carboxylic ester has been achieved for the first time through the Doebner–von Miller reaction. The high conversion efficiency and broad scope were demonstrated by synthesizing four quinoline-4-carboxylic esters linked COFs (QCE-COFs).
