摘　　要：金属有机骨架(MOFs)材料因其可设计的结构以及灵活可控的配位模式,在三阶非线性光学(NLO)领域引起了广泛的关注。与液体分散状态相比,MOFs在固体状态下的三阶NLO性能更为重要,这不仅可以深入了解MOFs本身所固有的光学性能,还有助于实现MOFs在光学器件中的实际应用。然而,由于散射的存在和透光率的限制,单独的MOFs材料难以直接实现固体状态下的三阶NLO性能研究,将MOFs制备成具有较好光学透过性的薄膜是研究其NLO性能最为可行的一种策略。MOFs薄膜不仅很好地继承了MOFs所固有的三阶NLO性能,而且还结合了薄膜的高透光率以及灵活的机械性能。基于此,本文分析总结了MOFs薄膜的制备方法及其NLO性能研究方面的相关工作,并根据目前MOFs薄膜在三阶NLO性能方面的研究现状对其未来发展予以了展望。Metal-organic framework(MOF) materials have attracted widespread attention in the field of third-order nonlinear optics(NLO) due to their customizable structure and flexible and controllable coordination modes.Compared with the liquid dispersion,the third-order NLO performance of MOFs in the solid state is particularly important.This provides a deeper understanding of the inherent optical performance of MOFs and helps realize the practical application in optical devices.However,it is difficult to directly study the NLO performance of MOFs in the solid state due to the presence of scattering and limitations of transmittance.In order to study the NLO performance of MOFs in the solid state,the most feasible strategy is to process MOFs into films with better transmittance.MOF film materials not only inherit the MOF inherent NLO performance but also combine the high transmittance and flexible mechanical properties of the film.This review analyzes and summarizes the preparation methods of MOF films and related work on NLO performance research.The prospects of MOF films in third-order NLO performance are proposed in this review.
