以N-乙基-4-乙酰胺基-1,8-萘亚胺为发光层的电致发光二极管

A DIODE UTILIZING N-Ethyl-4-Acetylamino-1,8-Naphthalimide AS A LUMINESCENTING LAYER

摘要: 合成了N-乙基-4-乙酰胺基-1，8-萘亚胺（NA）。结果表明，以NA为发光层，聚乙烯咔唑（PVK）为空穴传输层的多层薄膜发光器件Al/NA/PVK/ITO，在正相驱动电压为27.5V时，可获得150cd/m²的N-乙基-4-乙酰胺基-1，8-萘亚胺（NA）的黄绿光。

Abstract: The compound of N-ethyl-4-acetylamino-1,8-naphthalimide was synthesized. It is shown that the EL of the multilayer organic diode Al/NA/PVK/ITO, using N-ethyl-4-acetylamino-1,8-naphthalimide as a luminescenting layer, poly-（9-vinylcarbazole）（PVK） as a hole transporting layer, reaches yellow-green brightness as high as 150cd/m² when the injected voltage is 27.5V.
