Abstract: A new zinc-phthalocyanine peripherally substituted with methacryloyl groups was synthesized to be employed as 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
