Özet

We report herein, the synthesis, and spectral and electrochemical characterization of a series of phthalocyaninato zinc complexes where two biomedically potential structures; crown ether and phthalocyanine moities were gathered on the same molecule. The effect of number of crown ether moieties on metal ion binding properties, as well as proton sensitivity were investigated by using electronic absorption and fluorescence emission spectra. Spectral behaviors of the zinc phthalocyanine complexes fused with one crown ether; Zn[Pc(15C5)(C6H13)(6)] and four crown ether; Zn[Pc(15C5)(4)] in presence of Na+ and K+ ions were investigated into detail because of host-guest interactions of subjective ions with crown ether moieties, and compared with the crown ether free phthalocyanine; Zn[Pc(C6H13)(8)].
