The binding of representative alkali, alkaline earth, transition and heavy metal cations by 2-pyridylmethoxy derivatives (1b, in cone and partial cone conformations) of p-tert-butylhexahomotrioxacalixarene (1a) was assessed by spectrophotometry, microcalorimetry, proton NMR spectrometry and density functional theory methods.
