The starting reagents, chiral diamine 5 and calix[4]arene diacid chloride derivative 8, were prepared according to literature methods. H-1 and C-13 NMR data show that 9 exists in a cone conformation. In liquid-liquid extraction experiments, 9 exhibits selectivity for Li+ among the other alkali metals and a good extraction ability for transition metal cations, suggesting its potential use in different fields, such as a sensor for ions as well as for chiral molecules.en10.1080/10610270412331337321info:eu-repo/semantics/openAccesscalix[4]arenechiralityazoxacrown ethersolvent extractionArticle173251256Q3WOS:000228299600008Q2
