Abstract
The influence of complexation with some divalent transition metal cati ons on the electrical behavior of 4-amino-3-hydroxy-1-naphthalenesulfo nic naphthalenesulfonic acid has been studied over temperature range 2 94-450 K. The complexes behaved as typical organic semiconductors. The stability constants of different complexes were determined. Their com positions were characterised using conductometric titration and infrar ed techniques.
