Abstract: A new zinc phthalocyanine peripherally substituted with methacrylic groups was synthesized to be employed as a functional monomer in the formation of molecularly imprinted polymers as nucleoside receptors. The binding affinity and selectivity of the synthesized phthalocyanine towards nucleosides were evaluated by UV-vis titration experiments in CH2Cl2 at 298 K. The binding constant (Ka) and Gibbs free energy changes (-Δ G0) were calculated according to the modified Benesi-Hildebrand equation. Binding experiments showed that Ka of phthalocyanine with tri-O-acetyladenosine (TOAA) is 1.35 x 10^4, 500 times that of phthalocyanine with tri-O-acetyluridine (TOAU), indicating a high selectivity of the synthesized phthalocyanine derivative.
