| 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。由于卟啉具有较大的平面化π共轭结构等特性,因此被认为是优异的光学材料。在研究卟啉衍生物的非线性光学(NLO)性质时,为了提高卟啉的NLO性质,研究者们的工作主要集中在官能团的取代和芳环结构的扩展上,但是非线性极化率仍不满足工业化要求,同时卟啉还存在溶解性差等缺点,这些限制了卟啉NLO性质的进一步应用。多金属氧酸盐(多酸,POMs)是由前过渡金属元素与氧原子相互键合形成的一类金属氧簇化合物,有着丰富的电子和结构多样化等特点,是一种优良的电子接受体,多酸能够和卟啉相结合得到一类有较高稳定性和溶解性且具有较大NLO极化率的杂化物。为了能够较为全面地介绍目前卟啉-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系统性的综述。本文首先讲述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对薄膜类卟啉-多酸复合物材料的非线性光学影响,以及薄膜厚度对其在非线性光学性质的影响,最后,本文对该领域未来的发展提出了一些展望。这篇文章旨在为研究卟啉-多金属氧酸盐类物质并增强其非线性光学性质、提高实际应用价值提供研究思路。希望能够给卟啉-多酸复合物材料与非线性光学领域的同行研究者们提供一定的借鉴参考。 |

| 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. Porphyrin is considered an excellent optical material because it has characteristics such as large planarization π conjugated structure. In the study of the nonlinear optical (NLO) properties of porphyrin derivatives, in order to improve the NLO properties of porphyrins, the researchers" work mainly focuses on the substitution of functional groups and the expansion of aromatic ring structure, but the nonlinear polarizability still does not meet the requirements of industrialization, and porphyrins also have shortcomings such as poor solubility, which limit the further application of porphyrin NLO properties. Polyoxometalates (polyacids, POMs) are a class of metal-oxygen cluster compounds formed by the bonding of pre-transition metal elements and oxygen atoms, which has the characteristics of rich electronic and structural diversification, and is an excellent electron acceptor, and polyacids can be combined with porphyrins to obtain a class of hybrids with high stability and solubility and large NLO polarizability. In order to comprehensively introduce the current progress of porphyrin-polyacid complexes in the field of nonlinear optics, this paper systematically reviews the influence mechanism of different material structures on nonlinear optical properties. This paper first describes the research progress of powder porphyrin-polyacid composite materials synthesized based on non-covalent and covalent linkage, and then introduces the nonlinear optical effects of different construction methods on thin film porphyrin-polyacid composite materials, as well as the influence of film thickness on their nonlinear optical properties, and finally, this paper puts forward some prospects for the future development of this field. This paper aims to provide research ideas for the study of porphyrin-polyoxometalate substances, enhance their nonlinear optical properties, and improve their practical application value. It is hoped that it can provide some reference for peer researchers in the field of porphyrin-polyacid complex materials and nonlinear optics. |
