A Versatile Approach Toward Calix(Aza)crown Oligomers: Synthesis and Metal Ion Extraction. Journal of Macromolecular Science-pure and Applied Chemistry, 40(2), 95-106. Doi: 10.1081/MA-1200172531060-1325https://dx.doi.org/10.1081/MA-120017253https://hdl.handle.net/20.500.12395/18357Four new calix(aza)crown oligomers (5-8) have been synthesized by reacting p-tertbutylcalix[4](aza)crowns (3 and 4) with triethylene glycol ditosylate or 1,5-dibromopentane. Their phase transfer studies were performed by using liquid-liquid extraction procedure. It has been deduced from the observations that, the oligomers 5 and 7 are good extractants, whereas, oligomers 6 and 8 show different extraction behavior toward selected alkali (Li+, Na+, K+, Cs+) and transition metal cations (Ni+2, Cu+2, Co+2, Cd+2, Hg+2, Pb+2).en10.1081/MA-120017253info:eu-repo/semantics/openAccessCalix(aza)crownOligomersLiquid-liquid extractionAlkaliTransition metalsArticle40295106Q2WOS:000181514300001Q3
