Abstract

Herein, a novel fluorescent ionic covalent organic framework (BTTA–BDNP) based on a linked carbazole unit was constructed for the synchronous monitoring and capture of TcO₄⁻/ReO₄⁻. BTTA–BDNP has a fast fluorescence response time with a low detection limit (66.7 nM) for ReO₄⁻ (a non-radioactive substitute for TcO₄⁻). Meanwhile, the high charge density and hydrophobic skeleton of BTTA–BDNP enable it to exhibit rapid and selective trapping of ReO₄⁻ in complex environments.
