Abstract
AbstractThe emission and the ultraviolet spectroscopies were studied at 77 K in water/ethylene glycol or ethanol for polymers containing adenine, 6‐(methylamino)purine, and 6‐(dimethylamino)purine moieties, and for the corresponding dimeric and monomeric model compounds, in order to obtain more information about the nature and extent of the interactions between nucleic acid bases in the polymer chains. The emission spectra of the dimeric compounds and the polymers suggested the formation of excimers and the existence of strong interactions between the adenine rings of suitable compounds. These excimer emissions were not observed in the spectra measured in ethanol, and in water/ethylene glycol solutions at pH 2. The ultraviolet spectra suggested two kinds of base‐base interactions for plane in plane and coplanar arrangement.
