PREPARATION, MOLECULAR-STRUCTURES AND NOVEL MAGNETIC-PROPERTIES OF ORGANIC FERROMAGNETIC COMPOUNDS BY PYROLYSIS OF TRIPHENOXY-TRIAZINE AND BENZOGUANAMINE

The product obtained by the pyrolysis of a mixture of triphenoxy-triazine(TPTA) and benzoguanamine(BG) at 400-1000-degrees-C has exhibited novel ferromagnetic behaviour. The product with the highest spin concentration (1.4 x 10(20) spins g-1) was obtained when a TPTA/BG mixture of molar ratio 1.1:0.9 was pyrolysed at 700-degrees-C. The possible compound structures of the products prepared at 350-degrees-C and 600-degrees-C are proposed from the results of elemental analysis. The ferromagnetic behaviour is considered to be caused by parallel spins of the nitrogen and/or oxygen radicals in those structures.
