Abstract

This research investigates the development and sensing characteristics of innovative conjugated azo dye derivative obtained from dicyanoisophorones. This compound represents push–pull molecules with a donor-π-acceptor (D-π-A) structure. In our approach, we utilized Resorcinol as an electron-donating component, while strategically placing the cyano acceptor and diazo groups as donor units. The synthesized compound demonstrated significant solvatochromism, with their emission spectra ranging from green to red, indicating high responsiveness to environmental polarity. Furthermore, the addition of a dicyanovinyl group to a compound resulted in a highly sensitive colorimetric and fluorescent detector for cyanide ions, which induced a shift towards shorter wavelengths in the emission spectrum.

新型双氰异膦酮偶氮染料的设计与传感性能：溶剂变色与氰化物离子检测

本文研究了新型共轭偶氮染料衍生物的研制及其传感特性。该化合物为推挽分子，具有供体-π-受体（D-π-A）结构。在我们的方法中，我们利用间苯二酚作为给电子组分，同时策略性地将氰基受体和重氮基作为给电子单位。合成的化合物具有明显的溶剂致色性，其发射光谱范围从绿色到红色，表明其对环境极性具有较高的响应性。此外，在化合物中加入二氰乙烯基导致氰化物离子的高灵敏度比色和荧光检测器，这导致发射光谱向短波长方向转变。二氰异佛酮偶氮染料的合成、表征及应用（探针1）

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.
