Multifunctional In-MOF and Its S-Scheme Heterojunction toward Pollutant Decontamination via Fluorescence Detection, Physical Adsorption, and Photocatalytic REDOX.

A novel doubly interpenetrated indium-organic framework of has been assembled by In ions and highly conjugated biquinoline carboxylate-based bitopic connectors (HL). The isolated exhibits an anionic framework possessing channel-type apertures repleted with exposed quinoline N atoms and carboxyl O atoms. Owing to the unique architecture, displays a durable photoluminescence effect and fluorescence quenching sensing toward CrO, CrO, and Cu ions with reliable selectivity and anti-interference properties, fairly high detection sensitivity, and rather low detection limits.
