The solvent effects on the “cone”–“partial cone” equilibrium in tetramethoxy-p-t-butylcalixarene were studied for the first time. It was found that the concentration of the “cone” isomer is increased with increasing solvent polarity. The shift in the equilibrium was accounted for by the differece in the dipole moment between “cone” and “partial cone” isomers.
