Synthesis of an organic semiconductor by polimerization of 3-amino-1,2,4-triazole
We performed the polymerization of 3-amino-1,2,4-triazole (ATA), an insulator material, in acidic aqueous solution with ammonium persulfate, as oxidant agent. The new material, conveniently doped, turned out to be a semiconductor tetramer. The characterization was carried out using physical and spec...
