Sol-Gel Dipping Devices for H(2)S Visualization

In this contribution we report the synthesis and full characterization, via a combination of different spectroscopies (e.g., (1)H 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 H(2)S 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 H(2)S sensing device.
