Sol-Gel Dipping Devices for H2S Visualization

Sensors (Basel). 2023 Feb 10;23(4):2023. doi: 10.3390/s23042023.

Abstract

In this contribution we report the synthesis and full characterization, via a combination of different spectroscopies (e.g., 1H NMR, UV-vis, fluorescence, MALDI), of a new family of fluorescent zinc complexes with extended π-conjugated systems, with the final aim of setting up higher performance H2S sensing devices. Immobilization of the systems into a polymeric matrix for use in a solid-state portable device was also explored. The results provided proof-of-principle that the title complexes could be successfully implemented in a fast, simple and cost-effective H2S sensing device.

Keywords: fluorescence; hydrogen sulfide; portable sensors.
