Fluorene-based compound and organo-electroluminescent device using the same |
摘要 |
<p>Provided herein are fluorene-based compounds including a fluorene or a spirofluorene structure at both terminals and a spacer including one or more atoms between the both terminals. The invention further provides an organo-electroluminescent device having an organic layer in which the fluorene-based compound is introduced. The fluorene-based compound can be readily manufactured using dry and wet processes, and the organo-electroluminescent device using the same has excellent properties in color purity, internal and external efficiency, and thermal, optical and electrical stability.</p> |
