Pyrene-Integrated Cationic Organic Network: A Dual-Functionalized Platform for Simultaneous Chromate Detection and Sequestration.

ABSTRACT: Toxic heavy metal oxoanions constitute a major class of water contaminants, posing significant risks to both human health and ecosystems. Chromate (CrO₄ ^2-) is among the representative toxic heavy metal oxoanions, originating from various industrial processes and readily permeating water sources. Consequently, the efficient detection and removal of CrO₄ ^2- from water are of great importance. In this study, a series of pyrene-integrated cationic organic networks (CONs) with fluorescent properties and positively charged frameworks was synthesized. By modulating the pyrene unit content using a multivariate strategy, the CON with optimal fluorescence properties (CON-LDU8-30%) was obtained, synthesized with a 3:7 ratio of 1,3,6,8-tetra-(1H-imid
