摘要
N,N′- 双(二茂铁甲酰)乙二胺溶液吸收光谱测定发现,随β环糊精(βCD)浓度增大,体系吸收依次增强。在βCD 芘主客体体系中引入N,N′- 双(二茂铁甲酰)乙二胺,会改变芘的荧光发射光谱特征。循环伏安测定也表明,N,N′- 双(二茂铁甲酰)乙二胺βCD体系仅出现1个氧化峰,且氧化电位远高于自由N,N′- 双(二茂铁甲酰)乙二胺,这些结果说明,N,N′双(二茂铁甲酰)乙二胺中的2个二茂铁单元都可与βCD发生主客体作用。
The host-guest interaction between N,N′-bis(ferrocenoyl)diaminoethane and β-cyclodextrin((β-CD)) was studied. The absorption intensity of the solution containing N,N′-bis(ferrocenoyl)diaminoethane and β-CD increased with the increase of the β-CD concentration. The introduction of N,N′-bis(ferrocenoyl)diaminoethane altered the fluorescence emission spectrum of the β-CD and pyrene system. Only one (oxidative) peak was found in the cyclic voltammogram of the mixture of N,N′-bis(ferrocenoyl)diaminoethane with (β-CD), and the oxidation potential was significantly greater than that of the electro-active (compound) N,N′-bis(ferrocenoyl)diaminoethane in free state. These results show that as a guest, the two (ferrocene) groups in N,N′-bis(ferrocenoyl)diaminoethane can combine with β-CD simultaneously.
