Description Purine and pyrimidine derivatives occurring in nucleic acids posses an extraordinary high ability of self association at the electrode surface and can form there by a two-dimensional (2D) condensation a monomolecular compact film (self assembled monolayer SAM). The effects of halogen and methyl substituents on the 2D condensation of cytosine were studied. For the first time the 2D condensation of 5-fuorocytosine at the hanging mercury electrode was observed. The formation of 2D condensed layers of different cytosine derivatives at the Au(111) single crystal electrode we have observed as well.
