摘要
(1)H and (19)F NMR, and UV thermal melting studies have established that the stability of d(TCCCCC) is enhanced by the inclusion of a single 2'-fluorine-modified deoxycytidine residue; the results support the notion of the importance of sugar-sugar contacts in stabilising i-motifs in general and reveal that solvation is the cause of the instability of RNA equivalents.
