摘要

In this paper, we report on the formation and properties of a water-stabilized dimer comprising calix [4] arene-guanosine conjugate cG 2. The 1, 3-alternate calixarene cG 2 was poorly soluble in dry CDCl3 and gave an ill-resolved NMR spectrum, consistent with its nonspecific aggregation. The compound was much more soluble in water-saturated CDCl3. Two sets of well-resolved 1H NMR signals for the guanosine residues in cG 2, present in a ...
