Abstract

A single molecule sensor for several analytes is indeed desired by the scientists around the world due to obvious advantages. In this report we present a new class of Lophine incorporated azo dyes that has capacity of differential colorimetric detection of several metal ions. Interestingly the sensor was found to have pH dependent selective response towards several metals. The effective colorimetric detection was observed under neutral pH for Cu⁺², Al⁺³ and Fe⁺³ metal ions while under alkaline pH for Cu⁺², Zn⁺², Ni⁺² and Co⁺² metal ions. The detailed investigation of synthesis, characterization, spectroscopic analysis and application of the novel colorimetric sensor is presented here in. The sensor is effective under non-aqueous conditions which provides a complementary detection method for metals in non-aqueous environment.

Lophine采用偶氮染料作为多种金属离子的新型比色传感器。

由于具有明显的优势，一种适用于多种分析物的单分子传感器确实是全世界科学家所渴望的。在本报告中，我们提出了一类新的罗菲碱偶氮染料，具有多种金属离子的差比色检测能力。有趣的是，该传感器被发现对几种金属具有pH依赖的选择性响应。中性pH下对Cu+2、Al+3和Fe+3金属离子的比色检测有效，碱性pH下对Cu+2、Zn+2、Ni+2和Co+2金属离子的比色检测有效。本文对新型比色传感器的合成、表征、光谱分析及应用进行了详细的研究。该传感器在非水条件下有效，为非水环境中金属的检测提供了一种补充方法。

期刊介绍： Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
