<p>An electron transporting material which has a low driving voltage, excellent light emitting efficiency, and excellent durability is provided. The electron transporting material is composed of one compound presented by one among a formula (1-1), a formula (1-2), and a formula (1-3). The organic electroluminescence device includes an organic layer between a pair of electrodes and utilizes energy of exciton which is produced by re-joining electrons injected from a cathode and a positive hole injected from an anode for emitting lights.</p> |
