自１９８７年Ｔａｎｇ［１］报道了高效、高亮度的双层有机薄膜电致发光器件以来，电致发光材料的研究受到了广泛的关注．接着在１９９０年，英国剑桥大学Ｂｕｒｏｕｇｈｅｓ等［２］首次利用聚亚苯基乙烯（Ｐｏｌｙ（ｐｐｈｅｎｙｌｅｎｅｖｉｎｙｌｅｎｅ），ＰＰＶ）...
Since Tang [1] reported the efficient and high brightness double-layered organic thin-film electroluminescent device in 1987, much attention has been paid to the research of electroluminescent materials. Then in 1990, Buroughes et al [2] at Cambridge University first made use of Poly (p-phenylenevinylene) (PPV).
