A light-emitting compound that can be easily applied to vacuum vapor
deposition and exhibit long wavelength light is disclosed. Further, a
light-emitting element without inferior luminescence properties due to
the carbonization of a light-emitting compound during vapor deposition;
and a light-emitting device that is composed of the light-emitting
elements are also disclosed. A pyran derivative is represented by the
following general formula 1: ##STR00001## wherein R.sup.1 is a hydrogen
element or an alkoxy group.
