Organic amine groups in a neutral or acid conditions can be positively charged which have very good composite ability to guest molecules.
Diamine group can form complex with many metal ions , such as Cu2+,Cr3+,Mg2+ and so on. This provide new approachs to achieve artifical enzyme and highlight supramolecular researches.
Diamine also provide a secondary amine group and a primary amine group which can be linked to many functional group. This make diamine cyclodextrin an important intermediate for cyclodextrin synthsis.
Mercaptoacetic cyclodextrins derivatives extremely suitable for drug induction of anesthesia neuromuscular reversal.
