摘　　要：利用具有非线性光学（ＮＬＯ）活性的分散红（ＤＲＩ）掺杂高玻璃化转变温度的酚酞聚羟基醚（ＰＨＰ）和酚酞－联苯二酚－二氯二苯酮三元共聚物（ＰＰＨＢＰ－ＤＣＢＰｃｏｐｌｙｍｅｒ），得到了两种掺杂型非线性光学材料．升温电晕极化（ＣＯＰＥＴ）表明有较高的取向和较慢松驰，并推算了极化场强度Ｅｐ和二阶非线性系数ｄ３３。High glass transition temperature host polymers, poly (hydroxyether of phenophthalein)(PHP) and phenophthalein-biphenol-dichlorobenzophenone copolymer(PPH-BP-DCBD copolymer or TCP), were doped with Disperse Red 1 (DR1), respectively. Homogeneous thin films of PHP and TCP with the NLO molecules DR1 were obtained. The films exhibited higher orientational order and slow relaxation rate after corona-poling at elevated temperatures. The poling field Ep and the macroscopic second order NLO coefficient d33 were estimated.
