【摘要】 <正> 在有机物中,给体受体取代的偶氮化合物,由于它们具有几乎最高的二阶非线性光学效应以及作为一类新的、有前景的电光材料而倍受重视。在这方面,材料分子的非中心对称的有序排列是首先重要的。把非线性光学活性分子如偶氮化合物溶于聚合物中,再用电场极化方法得到分子有序排列的聚合物薄膜,这是目前认为最有效的材料宏观形态工程。更多还原

【Abstract】 The second harmoic properties of the torona onset poling at elevated temperature(CO-PET) and their temporal stabilities of three azo compounds are investigated. The (X)(2) values of the compounds were measured quantitatively and one of them was compared with literature value. Specifically, the effects of long chain on the amino group of azobenzene molecules upon the dipole orientation and second harmonic generation properties are discussed.更多还原
