对石墨烯等二维材料的研究进一步引发了人们对相似结构的其他有机、金属-有机二维层状纳米材料的浓厚兴趣.这些二维材料由于其优异的化学可剪裁性而受到关注,预期未来在电子器件、催化和小分子分离等方面具有广泛的用途.这篇综述系统地介绍了目前制备有机基二维材料的自上而下和自下而上的两大类方法,总结了有机基二维材料在生物识别、小分子分离和纯化以及电学方面的应用,最后讨论了有机基二维材料目前在制备和性质改进方面面临的问题和未来可能发展的研究方向. Research on two-dimensional materials, such as graphene, has further led to a keen interest in other organic, metal-organic two-dimensional layered nanomaterials of similar structure that have drawn attention due to their excellent chemical tailor- ability The future has a wide range of uses in electronics, catalysis, and small molecule separations, etc. This review systematically presents top-down and bottom-up approaches to the current generation of organic-based 2D materials, The applications of bi-dimensional materials in biometrics, small molecule separation and purification, and electrical applications are discussed. Finally, the current problems in the preparation and properties improvement of organic two-dimensional materials and the possible future research directions are discussed.
