Article Synopsis
- Chemically-sensitive Field Effect Transistors (ChemFETs) are used to assess the affinity of hydrophobic supramolecular scaffolds for aqueous anions, focusing on how receptor modifications impact this affinity.
- The study evaluates dodeca-butyl and dodecabenzyl bambus[6]uril to understand how steric effects influence the sensor's chemical selectivity.
- Results showed that ChemFETs with butyl funcionalized membranes significantly improved detection limits for perchlorate and nitrate compared to those with benzyl-functionalized membranes.
Hydrosulfide (HS) is the conjugate base of gasotransmitter hydrogen sulfide (HS) 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.
