文摘

Ytterbium(III) forms a complex with sulfonato-calix[5]arene in water with the calixarene assembled into the commonclay bilayered arrangement but having unusually dense packing of the calixarenes, which are squeezed together forming "impenetrable"bilayers. The efficiency of packing of the calixarene relates to its conformational flexibility, and it has implications in providing aprotective layer in stabilizing spheroidal nanoparticles.
