A new and innovative fluorescent structure was constructed on Cyclotriveratrylene affiliated to Dansyl chloride (DNSC) and was used to detect Cr (III) and Fe (III) among the various cations by using spectrofluorimetric method. The characterization of the new compound was carried out using the H-NMR, C-NMR, and ESI-MS techniques. The interaction and role of DNSC-CTV with cations was reviewed. A change in the spectra of absorption directed to the conclusion that there is substantial interaction of Cr (III) and Fe (III) with DNSC-CTV. Furthermore the interaction of the ligand DNSC-CTV with the metal ions Chromium (III) and Iron (III) showed quenching in the emission spectra. Quantum yield of the complexes were calculated and the stern volmer analysis was done to deduce the quenching mechanism of fluorescence to being either static or dynamic. The molecule DNSC-CTV was further studied with the help of computational methods such as molecular docking to study the binding interactions and properties of the molecule.
构建了一种与丹磺酰氯（DNSC）相关的新型创新荧光结构，并采用荧光分光光度法在各种阳离子中检测Cr（III）和Fe（III）。使用H-NMR、C-NMR和ESI-MS技术对新化合物进行了表征。综述了DNSC-CTV与阳离子的相互作用及作用。吸收光谱的变化表明Cr（III）和Fe（III）与DNSC-CTV存在大量相互作用。此外，配体DNSC-CTV与金属离子铬（III）和铁（III）的相互作用在发射光谱中表现出猝灭。计算了配合物的量子产率，并进行了斯特恩-沃尔默分析，以推断荧光猝灭机制是静态还是动态。借助分子对接等计算方法进一步研究了分子DNSC-CTV，以研究该分子的结合相互作用和性质。
