二维纳米材料由于其各向异性的结构和涌现特性而引起了人们的广泛兴趣。虽然各种无机纳米片是通过剥离制备的，但有机纳米片的设计和合成策略仍在发展中。在这里，我们报告的晶体控制合成导电和氧化还原活性的有机聚合物纳米片与可调的厚度和横向尺寸。虽然纳米片由经典的导电聚合物组成，如聚吡咯（PPy）和聚（3，4-乙撑二氧噻吩）（PEDOT），但一种新的晶体控制聚合方法提供了具有增强和特性的2D纳米材料。氧化聚合在有机氧化剂如醌衍生物的晶体表面上进行，在低温和环境压力下单体蒸气扩散。本发明的方法提供了对纳米片的横向尺寸和厚度的控制。所得的纳米片显示的特征和增强的性能的起源…
Two-dimensional nanomaterials have attracted much interest for their anisotropic structures and emergent properties. Whereas a variety of inorganic nanosheets are prepared by exfoliation, design and synthetic strategies of organic nanosheets are still developing. Here we report on crystal-controlled synthesis of conductive and redox-active organic polymer nanosheets with tunable thickness and lateral size. Although the nanosheets consist of classical conductive polymers, such as polypyrrole (PPy) and poly(3,4-ethylenedioxythiophene) (PEDOT), a new crystal-controlled polymerization approach provides 2D nanomaterials with enhanced and characteristic properties. Oxidative polymerization proceeds on the crystal surface of organic oxidants, such as quinone derivatives, with diffusion of the monomer vapor at low temperature under ambient pressure. The present method affords the control of lateral size and thickness of the nanosheets. The resultant nanosheets show the characteristic and enhanced properties origi...
