+ were determined. The template synthesis enhanced the affinity of the polymers to matrix forming cations by 6-8 kJ mol -1 .Design and experimental studies of supramolecu lar polymeric systems provide information on the prop erties of multicomponent self consistent natural as semblies and enable one to mimic their behavior at the molecular level. Immobilized calix[4]arenes are shown 1-7 to form supramolecular assemblies in the poly meric phase with alkali 1,2,4-6 and transition 3,5 metal cations, as well as ammonium. 7 Functionalization of immobilized calixarenes through introduction of carb oxyl, 3 phosphate, 5 and furyl(hydroxy)methyl 6 groups enhances the selectivity of interaction of the polymers with cations. An approach that provides prerequisites for the recognition of components of the assembly is the use of template synthesis of network polymers, whose three dimensional structure is formed according to the sol-gel technology on a matrix of organic and inorganic substrates. For instance, the template synthesis of polymeric pseudo crown ether, which is network on the matrix of Ni 2+ cations, induces a considerable in crease in the affinity of the polymer to the matrix forming cation. 8 We have previously synthesized network polymers on the matrix of Na + cations by the resol polycondensation of cis tetramethylcalix[4]resorcinarene, 1 cis tetraphenyl calix[4]resorcinarene, 2 and their derivatives 6 with form aldehyde. These polymers were shown 1,2,7 to interact with electrolyte solutions according to a cation exchange mode. It is of interest to study the effect of the matrix cations on the sorbability of the network calixarene con taining polymers obtained by the template synthesis. In the present work, we studied the ion exchange selectivity of network polymers synthesized by the polycondensation of cis 2, 8,14,20 tetraphenyl 4,6,10,12,16,18,22,24 octa hydroxycalix[4]arene (1) with formaldehyde using the sol-gel technology in the presence of cations Na + , K + , and Ba 2+ (Scheme 1).
