The nonlinear-optical (NLO) materials with second-harmonic-generation (SHG) response need to crystallize in the noncentrosymmetric space group. It is very difficult to control the synthetic conditions to solely form a noncentrosymmetric phase for the materials with noncentrosymmetric and centrosymmetric conformations. Herein, we found that the temperature and halogen anion play an important role during the formation procedure of the pure noncentrosymmetric or centrosymmetric phase for the halogen-based family of coordination polymers to yield hybrid materials with a phase-matching SHG response as well as inherit the primary excellent photonic property of organic linkers. Our results provide a good choice for the design and construction of novel materials with a particular photonic property.

用于卤素基光子配位聚合物家族的中心对称/非中心对称相的可控合成以增强相位匹配的第二谐波代响应

具有二次谐波产生 (SHG) 响应的非线性光学 (NLO) 材料需要在非中心对称空间群中结晶。对于具有非中心对称和中心对称构象的材料，很难控制合成条件以单独形成非中心对称相。在这里，我们发现温度和卤素阴离子在卤素基配位聚合物家族的纯非中心对称或中心对称相的形成过程中起着重要作用，以产生具有相位匹配 SHG 响应的杂化材料，并继承了有机连接体的主要优异光子特性。我们的结果为具有特定光子特性的新型材料的设计和构建提供了一个很好的选择。
