摘　　要：用可溶性前聚物法制备的聚 １，４萘乙炔（ Ｐ Ｎ Ｖ）制成单层有机电致发光器件。该器件阳极为 Ｉ Ｔ Ｏ，阴极为 Ｃａ，器件在正向偏压４ Ｖ 左右时开始发光，发光谱峰值为６０５ ｎｍ ，最高亮度为１４０ Ｃｄ／ｍ ２ 。文章分析了 Ｐ Ｎ Ｖ 发光器件的发光机理，并给出了器件的能带模型。An organic electroluminescent device utilizing poly(1,4 naphthalene vinylene)(PNV) via slouble precursor polymer has been demonstrated. The anode and cathode are ITO and Ca, respectively. The device begins to emit while 4.0 V, forward bias, the peak wavelength is about 605 nm the maximum brightness in about 140 cd/m 2. The emittig mechanism was analyzesed and the electronic band structure of PNV device was obtained.
