β-环糊精与中性红超分子包合物的形成与应用

Superamolecular Inclusion Complex Formation and Application of β CD with Neural Red

分别用微分脉冲极谱法和光度法测定了β－环糊精与中性红形成的包结化合物的包合稳定常数，并对两种方法的结果作以比较．利用β－环糊精与染料分子间的超分子作用作为介体的固定化方法，制成测定Ｈ２Ｏ２的酶传感器，具有较高的灵敏度和较好的稳定性．

CD forms the 1∶1 inclusion complex with Neutral red(NR) in aqueous media.The formation constant is determined using differential pulse polarography and spectrophotometry.This can be employed to immobilize dyes on an electrode,which behaves a high sensitivity and a stable electrochemical behavior by means of the supramolecular interaction between β CD and dye molecules.
