Recognition and sensing of nucleoside monophosphates by a dicopper(II) cryptate.

The dimetallic cryptate [Cu(2)(II)(1)](4+) selectively recognizes guanosine monophosphate with respect to other nucleoside monophosphates (NMPs) in a MeOH/water solution at pH 7. Recognition is efficiently signaled through the displacement of the indicator 6-carboxyfluorescein bound to the receptor, monitoring its yellow fluorescent emission. Titration… CONTINUE READING
