Abstract
Six different fluorobenzene or fluorobenzimidazole ribonucleosides and one abasic site were incorporated in oligoribonucleotides. Individual contribut ions of base stacking and solvation of the modified nucleosides could be de termined. In fluorobenzene . fluorobenzimidazole-modified base pairs a dupl ex stabilizing force was found that points to a weak F...H hydrogen bond. T he lipophilicity of the unprotected nucleosides were investigated by determ ination of 1-octanol water partition coefficients.
