An acylhydrazone-based colorimetric and fluorescent sensor (PAH-8) for the detection of F− and TFA/TEA has been studied. PAH-8 solution and organogel are highly selective and sensitive to F− among various tested anions in DMSO.
AHBP-8 can form a stable organogel and enhanced fluorescence emission has been observed after gelation. The AHBP-8 xerogel exhibited favorable mechano-fluorochromism behavior.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
