مستخلص: Hydrosulfide (HS - ) is the conjugate base of gasotransmitter hydrogen sulfide (H 2 S) and is a physiologically-relevant small molecule of great interest in the anion sensing community. However, selective sensing and molecular recognition of HS - in water remains difficult because, in addition to the diffuse charge and high solvation energy of anions, HS - is highly nucleophilic and readily oxidizes into other reactive sulfur species. Moreover, the direct placement of HS - in the Hofmeister series remains unclear. Supramolecular host-guest interactions provide a promising platform on which to recognize and bind hydrosulfide, and characterizing the placement of HS - in the Hofmeister series would facilitate the future design of selective receptors for this challenging anion. Few examples of supramolecular HS - binding have been reported, but the Sindelar group reported HS - binding in water using bambus[6]uril macrocycles in 2018. We used this HS - binding platform as a starting point to develop a chemically-sensitive field effect transistor (ChemFET) to facilitate assigning HS - to a specific place in the Hofmeister series. Specifically, we prepared dodeca- n -butyl bambus[6]uril and incorporated it into a ChemFET as the HS - receptor motif. The resultant device provided an amperometric response to HS - , and we used this device to measure the response of other anions, including SO 4 2- , F - , Cl - , Br - , NO 3 - , ClO 4 - , and I - . Using this response data, we were able to experimentally determine that HS - lies between Cl - and Br - in the Hofmeister series, which matches recent theoretical computational work that predicted a similar placement. Taken together, these results highlight the potential of using molecular recognition coupled with ChemFET architectures to develop new approaches for direct and reversible HS - detection and measurement in water and further advance our understanding of different recognition approaches for this challenging anion.
