Synthesis, Spectral Characterisation and Thermal Behaviours of Some New p-tert-Butylcalix[4]arene and Calix[4]arene-Esters Containing Acryloyl Groups

Abstract

The mono-, di-, tri-, and tetra-acryloyl esters of p-tert-butylcalix[4]arene and calix[4]arene were synthesised by reacting acryloyl chloride with sodium salts of p-tert-butylcalix[4]arene and calix[4]arene in THF. The structures of these compounds were characterised by IR, UV-VIS, H-1 NMR, and C-13 NMR. Thermal behaviour of the compounds were also examined by means of differential thermal analysis (DTA), thermogravimetry (TG), and derivative thermogravimetry (DTG). (C) 2012 Elsevier B.V.
