具有和石墨烯相似结构的自支撑有机二维纳米材料目前引起了科研人员的浓厚兴趣.这些二维材料具有优异的化学可剪裁性,预计未来在电子器件、有机催化和小分子分离等方面具有广泛的用途.本文首先系统地总结了常见的具有自支撑结构的有机二维纳米材料,进一步从自上而下和自下而上的两大类方法着手,介绍了目前常用的制备方法,然后对有机二维纳米材料在生物识别以及光电方面的应用进行了介绍,如生物分子识别、电子器件及荧光增强,最后讨论了目前有机二维纳米材料在制备和性质改进方面面临的问题和未来可能的重点研究方向.
Researchers are now interested in self-supporting organic two-dimensional nanomaterials with similar structures to graphene, which have excellent chemical tailor-ability and are expected to have future applications in electronic devices, organic catalysis, and small molecule separations A wide range of uses.This paper first systematically summarizes the common self-supporting structure of the organic two-dimensional nano-materials, further from the top-down and bottom-up approach to two major categories, introduced the current commonly used preparation methods, and then The applications of organic two-dimensional nanomaterials in biometrics and optoelectronics are introduced, such as biomolecule recognition, electronic devices and fluorescence enhancement. Finally, the problems and possible future problems in the preparation and properties improvement of organic two-dimensional nanomaterials The focus of research.
