Thiadiazole, light-emitting element, light-emitting apparatus, authentication apparatus, and electronic device

摘要

The thiadiazole represented by formula (2) or (4), when used as a light-emitting material in a light-emitting element, allows the light-emitting element to emit near-infrared light:;
in formulae (2) and (4), each R independently represents a hydrogen atom, an alkyl group, or a substituted or unsubstituted aryl group. There may be a ring formed by a carbon linkage between two adjacent R's.
