摘要
以杯[4]芳烃和浓硫酸为原料,合成了杯[4]芳烃四磺酸,即5,11,17,23-四磺酸基-25,26,27,28-四羟基杯[4]芳烃,对其进行紫外可见和热重与差热分析(TG-DTA),同时以KH2PO4-Na2HPO4为缓冲溶液,研究5,11,17,23-四磺酸基-25,26,27,28-四羟基杯[4]芳烃电化学行为。实验结果表明,当扫描电位在-1.2~0.8V时,有一不可逆的还原峰,还原峰电位在0.93V左右,且还原峰电位因扫描速度的改变而改变。
5,11,17,23-tetrasulphonated-25,26,27,28-tetrahydroxycalix[4]arene was synthesized from calix[4]arene and concentrated sulfuric acid as raw materials,and characterized with a UV-visible spectrophotometer,thermal gravimetric(TG)and differential thermal analysis(DTA);finally its electrochemical behavior was studied in the potassium dihydrogen phosphate-sodium hydrogen phosphate buffer solution,and the results show that there is an irreversible reduction peak at about 0.93V in the scan potential between -1.2~0.8V,and the reduction peak potential changed with scanning speed.
