Linearly Polarized light emission based on smectic phase reactive mesogen |
| 초록 |
Polymer light emitting diodes(PLEDs) have been developed during these decades. The light emitting polymer film with anisotropic properties can provide polarized emitting light, which can be applied in both LCD and OLED. The aligned liquid crystal having photoluminescent property is a promising material for polarized light emitting device applications. In this study, we synthesized a reactive mesogen containing photoluminescence core, which exhibits highly ordered smectic LC phase. The reactive mesogen showed UV absorption about 300 nm and PL emission in blue light region in the solid state. The anisotropic photoluminescence properties were investigated by polarized PL spectrometer. The multilayer PLEDs were also fabricated by spin-coating processes, and the electroluminescence properties was studied. The smectic phase light emitting layer showed higher luminescence dichroic ratio than that of the nematic phase, which is promising for the LCD and PLED applications. |
