- A new type of azacrown ether crosslinked chitosan was synthesized by reaction of chitosan with dihydroxy mesocyclic diamine activated by epoxidation.
- The classifications,synthesis,and application of the open chain azacrown ether compounds and their analogues have been reviewed in this paper.
- The parent azacrown ether 1,10-dioxa-4,7,13,16-tetraaza-18crown-6(L1) and its two acetic ether armed-derivatives(L2 and L3) were synthesized and characterized.
- In this paper we prepared a series of azacrown ethers with side chains of tropone rings and their derivatives by the reactivity of seven-membered aromatic tropone rings.
- The electronic structure and bond character of europium nitrate complex with azacrown (2, 2)(1, 7, 10, 16-tetraoxa-4, 13-diazacyclooctadecane), [Eu(NO_3)_2(2, 2)] NO_3, have been studied by means of XPS and INDO method.
- Synthesis and properties of novel azacrown ether resin
