Sol-Gel Dipping Devices for H2S Visualization

In this contribution we report the synthesis and full characterization, via a combination of different spectroscopies (e.g., H-1 NMR, UV-vis, fluorescence, MALDI), of a new family of fluorescent zinc complexes with extended pi-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.

Automated summary

In this study, a new family of fluorescent zinc complexes with extended pi-conjugated systems was synthesized and characterized. The complexes were investigated for their potential use in high-performance H2S sensing devices. The immobilization of the complexes into a polymeric matrix for solid-state portable devices was also explored. The results demonstrated that the complexes could be successfully applied in fast, simple, and cost-effective H2S sensing devices.
