Synthesis and Evaluation of Thermal Properties of Fluorinated Poly(aryl ether) Dendritic Structures Based on Calix[4]arenes

By using a convergence approach two new poly(aryl ether) dendritic structures carrying 4-fluorobenzyl bromide on the surface and calix[4]arenes as a core with G1 were synthesized for the first time. Fluorinated dendritic structures are connected through ether bonds on the lower rim of the calix[4]arene unit. Its structure was determined by ¹H-NMR and elemental analysis. The thermal stabilities of fluorinated dendritic structures, based on calix[4]arenes, were investigated using thermogravimetric analysis. The activation energies and thermal degradation of the structures were calculated with the Ozawa Method.
