Biindenylidene-3,10,30-trione: An Interesting Solvatochromic Molecule and Its Applications for Visual pH Detection and DCM Identification
The development of highly sensitive and visual analytical methods for monitoring pH change has always attracted great attention due to significant roles in various fields including food, environmental and biological systems. In this paper, a dual-response sensor for pH detection, [1,2']biindenylidene-3,1',3'-trione L, was synthesized from substrate indane-1,3-dione, and its structure was confirmed by 1H NMR, 13C NMR, ESI–MS and single crystals. Interestingly, sensor L exhibits solvatochromic properties and visualized color changes at different poplar solutions, and it can show significant changes in fluorescence intensity, UV–Vis absorbance and color at moderate acidic (pH = 3.52–5.03) and strong basic conditions (pH = 13.09–13.27) based on intramolecular proton transfer (IPT) mechanism. These results indicate that L can act as a double functional probe for the analysis and visual detection of pH change under moderate acidic and strong basic conditions in a quite narrow pH range. In addition, L can also selectively identify solvent CH2Cl2 by inducing larger blue-shift in wavelength and increase in fluorescence intensity, which means that it may be used as an indicator for monitoring trace amount of CH2Cl2. The potent applicantions for sensor L were also investigated and that it could conveniently be made into a series of strips for pH detection was indicated.
期刊介绍:
Journal of Solution Chemistry offers a forum for research on the physical chemistry of liquid solutions in such fields as physical chemistry, chemical physics, molecular biology, statistical mechanics, biochemistry, and biophysics. The emphasis is on papers in which the solvent plays a dominant rather than incidental role. Featured topics include experimental investigations of the dielectric, spectroscopic, thermodynamic, transport, or relaxation properties of both electrolytes and nonelectrolytes in liquid solutions.
