Abstract

A fluorescent chemosensor for Ag(I) as a new family of peripherally functionalized zinc-phthalocyanine, 2(3),9(10),16(17),23(24)-tetrakis-{6-(-benzofuran-2-carboxylate)-hexylth io} phthalocyaninatozinc(II) {Zn[Pc(β-S(CH2)6OCOBz-furan)4], (ZnPcBzF), (3), which was derivated from 6-(3,4-dicyanophenylthio)-hexyl-2-benzofuranate (BzF), (2), has been synthesized and fully characterized by elemental analysis, FT-IR, 1H and 13C NMR, MS (ESI and Maldi-TOF). An optical silver ion (Ag(I)) sensor based on the fluorescence quenching of benzofuran moiety and ZnPc core was developed. Both absorbance and fluorescence spectra of ZnPcBzF, (3) exhibit distinct changes in visible region in response to treatment with Ag(I) ion in solution. Such properties make compound ZnPcBzF, (3) intriguing candidates for incorporation into the transducer layer in optically based chemical sensors.
