2,4,6-Triazido-1,3,5-Triazine, 2,4,6-Triazidopyrimidine, and 2,4,6-Triazidopyridine as Precursors of Carbon Nitride Materials

摘要

The thermolysis of 2,4,6-triazido-1,3,5-triazine ( I ), 2,4,6-triazidopyrimidine ( II ), and 2,4,6-triazidopyridine ( III ) and its products were studied by DSC, mass spectrometry, IR spectroscopy, and electron microscopy. The thermal transformations of I gave planar nets formed by polyconjugated C–N bonds arranged into bundle aggregates. The thermolysis product of III consists of low-molecular compounds and has globular morphology. The thermolysis of II resulted in a mixture of products of both types, among which the planar nets were dominant. The relationship between the structure of the products of the thermal transformations of I , II , and III and the kinetic characteristics of these processes was discussed.
