Influence of 6-methyluracil and 5-hydroxy-6-methyluracil deposition quantity to properties of
supramolecular structure was investigated. It is shown, that 6-methyluracil net structure formation
occurred only when 10% of modifier was inflicted, while 1% of 5-hydroxy-6-methyluracil was enough to
form supramolecular net. Surface polarity was investigated by linear decomposition of retention
parameters method. It is shown, that after modification by 6-methyluracil polarity was significantly
increaseв due to donor-acceptor interaction, while modification by 5-hydroxy-6-methyluracil wasn’t
influence on the surface polarity
