Two different bridges were introduced at the 1,5:3,7-positions of p-tert-butycalix[8]arene I using a two-step alkylation procedure. A probable cation template effect in the introduction of the second bridge was evidenced. The obtained bis-bridged derivatives 3 possess encapsulating properties toward alkali cations modulated by the length and nature of the bridges.

Abstract: | Two different bridges were introduced at the 1,5:3,7-positions of p-tert-butycalix[8]arene I using a two-step alkylation procedure. A probable cation template effect in the introduction of the second bridge was evidenced. The obtained bis-bridged derivatives 3 possess encapsulating properties toward alkali cations modulated by the length and nature of the bridges. | |
