Abstract
Mean size, diffusion coefficient and hydrodynamic radii of p-tert-buty l-25,26,27,28-tetrahydroxycalix(4)arene (1), t-butyl-37,38,39,40,41,42 -hexahydroxycalix(6)arene (2) and ,50,51,52,53,54,55,56--octahydroxyca lix(8)arene(3) have been determined by dynamic laser (He-Ne) light sca ttering. It has been observed that the mean size of 1 varies with the change in its concentration in solution and temperature of experiments , while it remains constant for 2 and 3.
