Abstract

A series of triply bridged symmetrical tert-butylcalix [6] arene—10, 15-dihydro-5H-tribenzo [a, d, g] cyclononene conjugates have been synthesised in excellent yields. It has been observed that the synthesised multi-cavity molecular receptors retain the calix [6] arene and derivatised 10, 15-dihydro-5H-tribenzo [a, d, g] cyclononene units in their cone conformations in solution. While the employed alkyl spacers confer flexibility to the ...
