对叔丁基杯[6]芳烃与黑索金的配合研究

对叔丁基苯酚和甲醛在KOH催化下制备对叔丁基杯6]芳烃。用荧光光谱法研究了对叔丁基杯6]芳烃与黑索金(RDX)在溶液中的相互作用,结果表明对叔丁基杯6]芳烃与RDX在溶液中存在较强的配合作用,RDX的激发峰发生明显红移,荧光强度增强,主客体间发生了包合作用。通过对叔丁基杯6]芳烃-RDX配合物的发射光谱与紫外光谱分析,确定了在DMF溶液中对叔丁基杯6]-RDX配合物的化学计量比为1∶1,稳定常数为325.70。

Study on the P-Tert-calix[6]arene-RDX Supramolecular Complex

p-Tert-calix6]arene was synthesized with p-tertphenol and aldehyde as starting materials and KOH as catalyst.The reaction of p-tert-butylcalixarene and RDX in solution was investigated by fluorescence spectroscopy.When p-tert-butylcalix6]arene was added into the solution of RDX,the fluorescence and UV peaks all shifted towards long wavelength,and the peak intensities increased obviously,showing that a complex was formed between p-tert-butylcalix6]arene and RDX.With the fluorescence and UV spectra,the ratio of p-tert-butylcalix6]arene and RDX in the complex and the stability constant of the p-tert-butylcalix6]arene-RDX complex were determined,namely the ratio of p-tert-butylcalix6]arene and RDX was 1∶1 and the stability constant was 325.70.
