A variety of naphthobisc chalcogenadiazole (NTz, NOz) derivatives with a rigidtetracyclic structure are available, and polymer materials incorporating NTz and NOz have been reported to exhibit excellent semiconductor properties^1~2). In addition to NTz and NOz, various nitrogen-containing heterocyclic compounds can be synthesized from 1,2,5,6-tetraaminonaphthalene (TAN), which is a precursor for NTz synthesis. This material has high potential as a building block for constructing optical and electronic devices.
