- Abstract
- A red fluorescent compound, 4-(dicyanomethylene)-2-(1-pentylbicyclo[2,2,2]oct-4-yl)-6-(1-adamantyl-1,7,7-trimethyljulolidyl-9-enyl)-4H-pyran containing bulky adamantyl and 1-pentylbicyclo[2,2,2]octyl groups on a DCM backbone, was synthesized and characterized. In a red device using this material as a dopant, a luminous and power efficiency of 3.21 cd/A and 1.68 lm/W was achieved, respectively, at 20 mA/cm(2) with the CIE coordinates of (x = 0.60, y = 0.39) at 7.0 V.
