金属卟啉是一种重要的金属-有机复合物,在光电转换器件、催化、传感、医学等领域有着广阔的应用前景。对无机二维纳米材料(石墨烯或过渡金属硫属化合物等)的广泛研究促使金属-有机二维纳米材料成为当前的研究热点之一。本文针对金属-有机以及卟啉二维纳米材料的研究现状,在简要回顾金属-有机二维纳米材料发展历史的基础上,详细总结了金属卟啉单分散二维纳米晶和二维薄膜的制备方法,综述了其当前在太阳能电池、光电催化以及光学传感等方面的应用,最后讨论了金属卟啉二维纳米材料当前面临的研究问题及未来可能的发展方向。

Metalloporphyrins are a class of metal-organic complexes that exhibit a wide range of interesting properties with prosperous applications in photoelectric conversion devices, catalysis, sensors and medicines. Besides inorganic two-dimensional （2D） materials （e.g., graphene and transitional metal dichalcogenide nanosheets）, two-dimensional metal-organic nanosheets have also attracted considerable attention in recent years as interesting materials. Based on the rapid progress of two-dimensional metal-organic and porphyrinoid nanomaterials, this review aims to provide a brief review of the history of two-dimensional metal-organic nanomaterials, followed by a detailed summary of the synthetic methods used to prepare free-standing 2D nanosheets as well as 2D thin film of metalloporphyrins. We have also provided an up-to-date review of the applications of these materials in solar cells, photo- and electric catalysts as well as optical sensors, and a discussion pertaining to the problems associated with the synthesis, properties, and possible applications of metalloporphyrin 2D materials.
