Solid-state 87Rb NMR signatures for rubidium cations bound to a G-quadruplex.
We report the first solid-state 87Rb NMR characterization for rubidium cations bound to G-quartet structures formed by self-association of guanosine 5'-monophosphate and 5'-tert-butyl-dimethylsilyl-2', 3'-O-isopropylidene guanosine.
