Sažetak

Organometallic derivatives of nucleobases are characterized by distinctive biological and electrochemical properties. In this work, reduction potentials of ferrocenoyl-substituted nucleobases (uracil, 5-fluorouracil, and thymine) were measured by cyclic voltammetry and calculated by using density functional methods. Both experimental (281– 296 mV) and calculated (271–293 mV) values for reduction potential E°’ show that these conjugates are much better oxidants than the parent ferrocene system. In search for the computational model, which can successfully reproduce experimental results, the M06-2X functional appeared as the optimal method in terms of efficiency and accuracy.
