非线性光学（NLO）材料由于其在波长转换器和电光调制器方面的潜在应用而引起了人们的广泛关注。制备二次谐波材料的一种方法是使具有高二阶超极化率常数的不对称有机染料取向。在这里，我们展示了一维排列的不对称有机染料的金属有机框架（MOF）的孔。合成了具有Kagome型晶格的MOF，将有机染料封装在其一维孔中。有机染料沿着一维孔取向，这通过线偏振激发光下的荧光证实。
Nonlinear optical (NLO) materials have attracted considerable attention due to their potential applications for wavelength converters and electro-optical modulators. One way to fabricate SHG materials is to align asymmetric organic dyes with high second-order hyperpolarizability constants. Here, we demonstrate one-dimensional alignment of asymmetric organic dyes in pores of metal-organic framework (MOF). MOF with Kagome-type lattice was synthesized to encapsulate the organic dyes in its one-dimensional pores. The organic dyes were oriented along with the onedimensional pores, which was confirmed by fluorescence under linearly-polarized excitation light.
