Self-assembled monolayers of different conformers of p-tert-butylcalix[4]crown-6 derivatives and their metal cation recognition properties

Two isomers of p-tert-butylcalix[4]crown-6 derivatives form stable self-assembled monolayers (SAMs) by taking advantage of the adsorption of bis-thioctic ester on gold electrodes, and their Cs+ recognition is completely dependent on the conformational orientation of the compounds.
