文摘

The formation of supramolecular polymeric aggregates with a molecular mass of 100 kDa in a nonaqueous solutionfrom a telechelic dimer of isopropylidene guanosine in the presence of K⁺ ions is reported. The possible structureof macromonomers resulting from the development of G₄ quartets was deduced from DOSY NMR, circular dichroismspectra, and dynamic light scattering measurements.
