Synthesis, spectral characterisation and thermal behaviours of some new p-tert-butylcalix[4]arene and calix[4]arene-esters containing acryloyl groups

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, 1H NMR, and 13C NMR. Thermal behaviour of the compounds were also examined by means of differential thermal analysis (DTA), thermogravimetry (TG), and derivative thermogravimetry (DTG).
