Thiazole-Decorated PCN-700 Metal–Organic Frameworks for Diclofenac Luminescence Sensing and Adsorption in Wastewater

Abstract

The defective sites on the eight-connected [Zr 6 O 4 (OH) 8 (H 2 O) 4 ] 8+ nodes of the metal−organic framework (MOF) PCN-700 are the anchoring points for its postsynthetic decoration with extra linkers via solvent-assisted linker incorporation (SALI). The thiazolo [5,4-d]thiazole-2,5-dicarboxylic acid (H 2 TTz) and the newly prepared 2,2′-(1,4-phenylene)bis(4methylthiazole-5-carboxylic acid) (H 2 TzPhTz Me ) have been inserted into PCN-700 to obtain the mixed-linker MOFs (MIXMOFs)
