Ag(I)外周功能化锌-酞菁新家族的荧光化学传感器，2(3),9(10),16(17),23(24)-四基斯-{6-（-苯并呋喃-2-羧酸盐）-己基硫}酞菁锌（II） [Zn[Pc(β - s （CH2)(6) ocobz -呋喃）(4)],（ZnPcBzF）。(3)由6-（3,4-二氰苯基硫代）-己基-2-苯并呋喃酸酯（BzF）和(2)合成，并通过元素分析、FT-IR、H-1和C-13 NMR、质谱（ESI）和Maldi-TOF进行了表征。研制了一种基于苯并呋喃部分和ZnPc芯的荧光猝灭的光学银离子（Ag(l)）传感器。溶液中Ag(1)离子处理后，ZnPcBzF,(3)的吸光度和荧光光谱在可见光区都发生了明显的变化。这些特性使得化合物ZnPcBzF(3)成为光学化学传感器中传感器层的有趣候选者。2009爱思唯尔有限公司版权所有。
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)-hexylthio} phthalocyaninatozinc(II) [Zn[Pc(beta-S(CH2)(6)OCOBz-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, H-1 and C-13 NMR, MS (ESI and Maldi-TOF). An optical silver ion (Ag(l)) 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(l) ion in solution. Such properties make compound ZnPcBzF, (3) intriguing candidates for incorporation into the transducer layer in optically based chemical sensors. (C) 2009 Elsevier Ltd. All rights reserved.
