Two new crosslinked-crown ethers (CCTS-NACH-B-15-C-5 and CCTS-NACH-B-18-C-6) were synthesized by the reaction of crosslinked chitosan (CCTS-NH 2 ) with 4Π-formyl benzo-15-crown-5 and 4Π-formyl benzo-18-crown-6. Their structures were confirmed with elemental analysis, infrared spectra analysis, solid

## Abstract Azacrown ether chitosan (CTSC) was synthesized by the reaction of chitosan with __N__βallyl benzo 15βcrownβ5 crown ether. Azacrown ether crosslinked chitosan (CCTSC) was prepared by the crosslinked reaction of CTSC and epichlorodydrin. Their structures were confirmed by infrared spectra
The novel azacrown ether chitosan derivatives (CCAE-I, CCAE-II) were prepared by reaction between crosslinked chitosan with epoxy-activated azacrown ethers. Their structures were confirmed by elemental FTIR spectra analysis and X-ray diffraction analysis. The adsorption and selectivity properties of
Eight novel polymeric pseudocrown ether (PPCE) resins containing azacrown and azathiacrown ethers were prepared by chemical reactions of the precursor of 1-chloro-2,3-epoxypropane, 1-(2-chloroethoxy)-2,3-epoxypropane, 1-chloro-2,3-epithiopropane, and 1-(2-chloroethoxy)-2,3-epithiopropane with trieth
Two novel chitosan derivatives-crosslinked chitosan dibenzo-16-c-5 acetate crown ether (CCTS-1) and crosslinked chitosan 3,5-di-tert-butyl dibenzo-14-c-4 diacetate crown ether (CCTS-2)-were synthesized by the reaction of crosslinked chitosan with dibenzo-16-c-5 chloracetate crown ether and 3,5-di-te
