Conformationally Restricted Ratiometric Fluorescent Receptor for the Recognition of Adipate

摘要

Qualitative and quantitative detection of anions is an inspiring research area in chemical, biological, and environmental sciences. Among the anion sensing, dicarboxylate recognition is of interest because of the pronounced applications of dicarboxylates in industry and biological systems. For the estimation of minute quantities of dicarboxylates, the fluorescence spectroscopy is ideally suited owing to its high sensitivity. Most of the reported chemo-sensors exhibit single-wavelength detection of fluorescence intensity, which is the simplest and most commonly used procedure. However, this procedure has suffered from various factors such as instrument effects (the brightness of the light source or the sensitivity of the detector), concentration of sensor molecules, and environmental effects. The ratio-metric fluorescence methods that are being used to tackle these problems operate by applying the intensity ratios of two different emission wavelengths.
