In this paper, we described a donor-acceptor-donor type red fluorescence material, which have the bulky trimethylsilane groups in the donor moieties. To explore the electroluminescence properties of these materials, multilayered OLEDs were fabricated with a device structure of ITO/2-TNATA (60 nm)/NPB (40 nm)/Red 1 (2%):rubrene (50%):Alq3 (30 nm)/Alq3 (60 nm)/Liq (3 nm)/Al (100 nm). A device using Red 1 as the dopant material showed a maximum luminance of 5138 cd/m2 at 12.0 V, maximum luminous efficiencies of 1.62 cd/A, and maximum power efficiencies of 1.04 lm/W. The Commission Internationale de L'Eclairage coordinates of this device was (0.67, 0.33) at 7.0 V, which indicated stable color chromaticity at various voltages.
在本文中，我们描述了一种给体-受体-给体型红色荧光材料，其给体部分含有庞大的三甲基硅烷基团。为了探究这些材料的电致发光性能，制备了具有ITO/2-TNATA（60纳米）/NPB（40纳米）/Red 1（2%）:红荧烯（50%）:Alq3（30纳米）/Alq3（60纳米）/Liq（3纳米）/Al（100纳米）器件结构的多层有机发光二极管。以Red 1作为掺杂材料的器件在12.0伏时显示出最大亮度为5138坎德拉每平方米，最大发光效率为1.62坎德拉每安培，最大功率效率为1.04流明每瓦。该器件在7.0伏时的国际照明委员会坐标为（0.67, 0.33），这表明在不同电压下颜色色度稳定。
