PURPOSE: Provided is a pyrromethene metal complex for use as a fluorescent dye to form a light emitting device(LED). The light emitting device includes a material which brings about light emission between an anode and a cathode. CONSTITUTION: The pyrromethene metal complex is represented by formula(1): wherein each of R¬1, R¬2 and L is the same or different from each other, is a group selected from hydrogen, alkyl, cycloalkyl, aralkyl, alkenyl, cycloalkenyl, alkynyl, hydroxyl, mercapto, alkoxy, alkylthio, aryl ether, aryl thioether, aryl, heterocyclic, halogen, haloalkane, haloalkene, haloalkyne, cyano, aldehyde, carbonyl, carboxyl, ester, carbamoyl, amino, nitro, silyl, siloxanyl, and fused aromatic and alicyclic rings each formed with an adjacent substituent; M is a metal having a valence of m and is selected from boron, beryllium, magnesium, chromium, iron, nickel, copper, zinc, and platinum; and each of Ar¬1 to Ar¬5 is an aryl group. |
