A multilayer electroluminescent device comprising a cathode, an anode, a light emitting layer, and a layer disposed between the cathode and anode containing a dihydrophenazine compound is disclosed.
A cascaded organic electroluminescent device includes an anode, a cathode, and a plurality of organic electroluminescent units disposed between the anode and the cathode, wherein the organic electroluminescent units comprise at least a hole-transporting layer and an electron-transporting layer. The device also includes a connecting unit disposed between each adjacent organic electroluminescent unit, wherein the connecting unit comprises, in sequence, an n-type doped organic layer, and a p-type doped organic layer wherein the p-type doped organic layer includes a dihydrophenazine derivative compound.

wavelengths was confirmed. The reaction rate is in a range of 111–208 μg min−1 with these LEDs. The mechanism of the reaction was examined and the experimental results exclude the intermolecular interaction such as the Förster resonance energy transfer, the intermolecular charge transfer, the photoinduced electrontransfer and the formation of an exciplex. The formation of the reactive oxygen species was verified
用中心发射波长在 365 至 595 nm 范围内的 LED 研究了 5,12-二氢苯并[ b ]吩嗪 (DHBP) 的光化学稳定性。在高达 516 nm 的波长下观察到DHBP 到苯并[ b ]吩嗪 (BP) 的光化学转化。DHBP 不吸收 490 和 516 nm 的光,但证实了 DHBP 光活化自催化氧化为具有这些波长的 BP。反应速率在 111–208 μg min -1范围内使用这些 LED。对反应机理进行了研究,实验结果排除了分子间相互作用,例如福斯特共振能量转移、分子间电荷转移、光致电子转移和激子复合物的形成。用电子顺磁共振验证了活性氧的形成,这表明其在合成中的潜力。当使用太阳光作为光源时,1 mg mL -1 DHBP的氧化速率为393 μg min -1。在类似化合物上也观察到相同的自催化氧化,它可用于生产用于半导体的无金属有机物质。
