Research Progress in Nonlinear Optics of Porphyrin-Polyoxometalate Composite Materials

随着工业生产、国防科技、医药研究等诸多领域对激光技术日益增长的需求,非线性光学材料逐渐成为人们关注并研究的重点。卟啉具有较大的π共轭结构,是优异的光学材料,但是在实际应用中其非线性极化率和溶解性仍受到制约。多金属氧酸盐(多酸)具有很强的电子捕获能力。为了较为全面地介绍卟啉-多酸复合物在非线性光学领域方面的进展,本文基于不同材料结构对非线性光学性能的影响机制进行综述。首先介绍了基于非共价和共价连接方式合成的粉体类卟啉-多酸复合物材料在结构和机理方面的研究进展;然后,介绍了不同的构筑方式以及薄膜厚度对薄膜类卟啉-多酸复合物材料的非线性光学性质的影响;最后,对卟啉-多酸复合物材料的设计与合成进行了展望。

With the increasing demand for laser technology in many fields such as industrial production,national defense science and technology,and pharmaceutical research,nonlinear optical materials have gradually become the focus of people’s attention and research.Porphyrins have a largeπconjugate structure and are excellent optical materials,but their nonlinear polarizability and solubility are still limited in practical applications.Polyoxometalates(polyacids)have a strong electron trapping ability.In order to comprehensively introduce the progress of porphyrin-polyacid complexes in the field of nonlinear optics,this paper reviews the influence mechanism of different material structures on nonlinear optical properties.The research progress of powder porphyrin-polyacid composite materials synthesized based on non-covalent and covalent ligation methods is first introduced,and then the nonlinear optical effects of different construction methods on thin film porphyrin-polyacid composite materials and the influence of film thickness on their nonlinear optical properties are introduced,and finally,the design and synthesis of porphyrin-polyacid composite materials are prospected.
