发展了一种简单、低成本的制备大面积毫米级有机二维单晶的方法。二维晶体是在任意非晶衬底上制备的，具有单分子层的厚度和完美的长程晶序。高性能的OFFERS制造使用单层晶体作为半导体层和载流子迁移率表现出没有厚度依赖性，证实了单层的电荷传输效率。
A facile and low-cost solution method is developed to fabricate large-area organic 2D single crystals on a millimeter scale. The 2D crystals are prepared on arbitrary non-crystalline substrates with thicknesses of a single molecular layer and perfect long-range crystalline order. High-performance OFETs are fabricated using the monolayer crystals as the semiconducting layer and the carrier mobility exhibits no thickness dependence, confirming the efficiency of the monolayer for charge transport.
