Abstract

A novel methodology for the site-directed introduction of a functional group in the vicinity of β- cyclodextrin (CD) on the backbone of branched poly (ethylenimine)(PEI) is developed. Site- directed or random attachment of 1, 5, 9-triazacyclododecane (TC) to CD-containing PEI followed by acetylation of the primary and secondary amines of the polymer backbone produced [TC–CD] SDAcPEI or [TC–CD] RanAcPEI, respectively. By the addition of Ni (II), ...
