Abstract—The water sorption isotherms on seven samples of crystalline calix[4]arenes were obtained by the
isopiestic method. The experimental isotherms were described by the Harkins–Jura equation for condensed
films. The conclusion was made that water was adsorbed on the surface of calixarene crystals or through pores
of a fairly large diameter with the formation of a condensed film.
