Abstract

Excellent quadratic non-linear optical (ONL-2) properties of the poly(2,5-(but-2-ynyloxy) benzoate, containing a polar diacetylene as a chromophore, were found. According with the Maker fringes method, oriented polymer films showing an order parameter of ∼0.23 can display outstanding and stable Second Harmonic Generation (SHG) effects under off-resonant conditions (SHG-532 nm). Also, the macroscopic non-linear optical (NLO)-coefficients were evaluated under the rod-like molecular approximation, obtaining: and in the order of 280 ± 10 and 100 ± 10 pm V, respectively. The mechanical and chemical properties, in addition to the large ONL-2 coefficients exhibited by this polymer, make it a promising organic material in the development of optoelectronic/photonic devices.

摘要

发现了含有极性二乙炔作为发色团的聚（2,5 -（丁 - 2 - 炔氧基）苯甲酸酯）具有优异的二次非线性光学（ONL - 2）性质。根据Maker条纹法，显示约0.23的有序参数的取向聚合物薄膜在非共振条件下（SHG - 532 nm）可表现出出色且稳定的二次谐波产生（SHG）效应。此外，在棒状分子近似下评估了宏观非线性光学（NLO）系数，分别得到约280±10和100±10 pm V量级的系数。除了该聚合物表现出的大的ONL - 2系数外，其机械和化学性质使其成为光电子/光子器件开发中有前景的有机材料。
