Tetracycline (TC), a broad-spectrum antibiotic extensively used in human and veterinary medicine, persists in aquatic environments, contributing to antimicrobial resistance and ecological toxicity. In this study, we present a highly stable luminescent tris(2-carboxyethyl) isocyanurate crystal (<strong>1</strong>) as a multifunctional material for the simultaneous detection and degradation of TC in aqueous systems.

The exceptional performance of (<strong>1</strong>) can be attributed to its strong hydrogen bonding interactions, efficient electron transfer mechanisms, and robust structural stability in aqueous environments.
