Thermal behaviour and electrical properties of some biologically active sulphonamide Schiff bases

Abstract The sulphonamide Schiff bases are thermolabile and undergo thermochromism and thermal decomposition after melting. The electric conduction properties of the Schiff bases were studied. In addition, the current-voltage dependence of the sulphonamide Schiff bases was investigated. This showed that the Schiff bases under investigation have ohmic conduction which is temperature independent.
