The conformational behaviour of thiacalix[4]arenes: the pinched cone - pinched cone transition

Abstrakt

Work is focused on the dynamics and thermodynamics of the pinched cone-pinched cone interconversion of calix[4]arenes. Behaviour of methylene bridged non-substituted tetraalkoxycalix[4]arene and its tetraalkoxythiacalix[4]arene analogue is compared.
