A highly selective fluorescent chemosensor for guanosine-5′-triphosphate via excimer formation in aqueous solution of physiological pH
N Ahmed, B Shirinfar, IS Youn, A Bist… - Chemical …, 2012 - pubs.rsc.org
A new water-soluble and fluorescent imidazolium-anthracene cyclophane 1 effectively
recognizes and differentiates the biologically important GTP and ATP in 100% aqueous
solution of physiological pH 7.4. Fluorescence, 1H-NMR spectra and ab initio calculations
demonstrate that excimer formation and fluorescence enhancement occur upon GTP and
ATP binding, respectively, through (C–H)+⋯ A− hydrogen bond interactions.
