  In situ Cu(II)-containing chiral polymer complex sensor for enantioselective recognition of phenylglycinol

  摘要：

  A chiral polymer P1 was synthesized by the polymerization of 2,5-dibutoxy-1,4-di(benzaldehyde)-1,4-diethynylbenzene (M-1) with (R,R)-1,2-diaminocyclohexane (M-2) via Schiff's base formation, and the chiral polymer P2 could be obtained by the reduction reaction of P1 with NaBH4. P2 can serve as a "turn-off" fluorescent sensor toward Cu2+ and Ni2+. The in situ generated Cu(II)-containing polymer complex of P2 (Cu(II)-P2) can exhibit remarkable "turn-on" fluorescence enhancement response and considerable enantioselectivity toward unmodified phenylglycinol via a ligand displacement mechanism. More importantly, (R,R)-Cu(II)-P2 solution can turn on bright blue fluorescence color change again upon addition of L-phenylglycinol under a commercially available UV lamp, which can be clearly observed by the naked eyes for direct visual discrimination at low concentration. The simple, rapid and sensitive benign process makes this protocol promising for recognition of phenylglycinol enantiomers. (C) 2012 Elsevier Ltd. All rights reserved.

  direct visual discrimination at low concentration. More importantly, the addition of trivalent metal cations can lead to a most pronounced change of CD spectra of the chiral polymer indicating this kind chiral sensor can also be used as a sole probe for selective recognition of trivalent metal cations based on CD spectra. © 2013 Wiley Periodicals, Inc.

  通过4,4'-（（（2,5-二丁氧基-1,4-亚苯基））双（乙炔-2,1-二基）的聚合反应设计并合成了一种新颖的基于手性（S）-BINAM的荧光聚合物传感器）-二苯甲醛（M-1）与（S）-2,2'-联萘二胺（S - BINAM，M-2）通过希夫的基地阵型。当在市售紫外灯下添加三价金属离子时，所得的螺旋手性聚合物传感器显示出显着的“开启”亮蓝色荧光色。肉眼可以清楚地观察到这种变化，以便在低浓度下直接进行视觉辨别。更重要的是，添加三价金属阳离子可导致手性聚合物CD光谱发生最明显的变化，表明这种手性传感器也可用作基于CD光谱选择性识别三价金属阳离子的唯一探针。©2013 Wiley Periodicals，Inc.
