Luminescent metal-organic frameworks integrated hydrogel optical fibre as a photoluminescence sensing platform for fluorescence detection

Abstract

A novel and robust sensing platform based on metal-organic frameworks (MOFs) integrated hydrogel optical fibre is proposed for fluorescence detection for the first time. The core-clad structure of hydrogel optical fibre with a step index profile can achieve efficient excitation light delivery and luminescent emission collection. Meanwhile, immobilization of luminescent MOFs in the core of hydrogel fibre prevents the MOFs from directly contacting with the harsh environment, while reserving channels for the analyte penetration and interaction with the MOFs. In the representative experiment, the water and thermo stable EuNDC (H2NDC=1,4-naphthalenedicarboxylic acid) is synthesized as fluorescence material for highly selective detection of explosive picric acid (PA). Fluorescence quenching is visible to the naked eye at a concentration of PA as low as 5.7 ppm. The EuNDC integrated hydrogel optical fibre enables the realization of highly selective detection toward explosive picric acid (PA) over other nitroaromatic compounds and metal ions, which demonstrate the potential of hydrogel fibre as a portable, robust sensing platform for highly selective, on-site and real-time quantitative monitoring.
