Supramolecular Polymers Based on the Quadruplex Formation of Ditopic Guanosine Macromonomers in Nonaqueous Media

The formation of supramolecular polymeric aggregates with a molecular mass of 100 kDa in a nonaqueous solution from a telechelic dimer of isopropylidene guanosine in the presence of K+ ions is reported. The possible structure of macromonomers resulting from the development of G4 quartets was deduced...

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