PYRAN DERIVATIVE, METHOD FOR MANUFACTURING THE SAME, AND LIGHT-EMITTING ELEMENT CONTAINING THE PYRAN DERIVATIVE

摘要

A light-emitting compound that has excellent carrier transportation properties and that can exhibit long wavelength light is disclosed. Further, a method for manufacturing the light-emitting compound in a high yield is disclosed. The disclosed light-emitting compound is a pyran derivative as represented by general formula 1: wherein A¹ and A² are individually a pi-conjugated system group having 6 to 16 conjugating carbon atoms; X¹ is a dialkylamino group; and Y¹ is a diarylamino group or an alkylarylamino group.
