A complex of anthracene with methyl-beta-cyclodextrin (A-Me-β-CD) having fluorophoric characteristics was obtained in aqueous medium. Spectroscopic and thermal analyses of the complex were performed by Fourier transform infrared spectroscopy and differential scanning calorimetry-thermogravimetry. The interaction of Me-β-CD and anthracene was also analyzed by means of spectrometry by a UV–Vis spectrophotometer. The stoichiometry of the complex was determined by the Benesi–Hildebrand method. The complex formation constant was found to be (42 ± 3) × 103 L·mol−1. The Gibbs energy and excited singlet state energy were calculated. The mechanism of the quenching effect of Co(II) and Ni(II) metals in the inclusion complex was studied. The Stern–Volmer constant, bimolecular quenching rate constant, lifetime and approximate activation energy values were determined, and the quenching was found to be diffusion controlled dynamic quenching. In addition, with the energy band calculations made, it was shown by means of Taug curves that electron transfer was made to Ni and Co metals from the complex fluorophore group in the quenching mechanism.

合成和表征蒽的主客体包封的实验研究，以及钴和镍的淬火效果

在水性介质中获得了具有荧光团特征的蒽与甲基-β-环糊精（A-Me-β-CD）的复合物。通过傅里叶变换红外光谱和差示扫描量热法-热重法对配合物进行光谱和热分析。Me-β-CD 和蒽的相互作用也通过紫外-可见分光光度计的光谱分析进行了分析。复合物的化学计量由 Benesi-Hildebrand 方法确定。发现络合物形成常数为（42±3）×103 L·mol-1。计算吉布斯能量和激发单线态能量。研究了包合物中Co(II)和Ni(II)金属的淬火作用机理。Stern-Volmer 常数，双分子猝灭速率常数，确定了寿命和近似活化能值，并且发现猝灭是扩散控制的动态猝灭。此外，通过能带计算，通过 Taug 曲线表明，电子从淬灭机制中的复合荧光基团转移到 Ni 和 Co 金属。
