“…This method requires a minimal amount of material and has been used previously in the characterization of similar water-soluble calixarenes. 20 When the concentration of anionic 6b was increased from 0.2 to 5 mM, the chemical shifts of several hydrogens changed significantly. The largest change in the chemical shift was observed for the endo methylene bridge (ArCH 2 -Ar) hydrogens.…”

Several water-soluble calix [4]arenes were synthesized via Huisgen 1,3-dipolar cycloaddition between azides and alkynes. Cationic, anionic, and nonionic calixarenes were prepared from a common azidocalixarene intermediate. Azidocalixarenes performed better than alkynylcalixarenes as precursors. The aggregation behavior of the water-soluble calixarenes was studied by 1H NMR spectroscopy. Disciplines Chemistry CommentsReprinted (adapted)

“…The water-soluble calixarenes are obtained by the introduction of anionic (sulfonate) groups on the upper or lower rim, or cationic (ammonium) groups on the upper rim [31]. Calix[n]arenes possess architecture similar to CDs but have many conformational isomers because of rotational modes of the phenolic unit.…”

“…[10,15,16] Из-вестно, что водорастворимые каликсарены с гидрофоб-ными заместителями (н-C 6 H 13 , н-C 7 H 15 ), находящиеся в конформации «конус», образуют в растворе агрегаты мицеллярного типа за счет гидрофобных взаимодей-ствий, [17] а для амфифильных каликсаренов в конформа-ции «1,3-альтернат» характерно образование ламелл. [18] Обзор литературы показывает, что за последние годы синтезировано значительное количество произво-дных каликс[4]резорцина и изучены их агрегационные и каталитические свойства в отсутствие и в присут-ствии ПАВ, в водно-органических и неводных средах.…”
