One-Pot Preparation of Mechanically Robust, Transparent, Highly Conductive and Memristive Metal-Organic Ultrathin Film
摘要：
2D柔性电子产品的未来依赖于以简单但可控的方式制备具有机械鲁棒性和柔性的材料的导电薄膜。在这方面，金属-有机化合物由于其结构、化学和功能的多样性而呈现出优于无机层状晶体的优势。虽然大多数金属有机化合物通常是批量制备的，但最近的研究表明，它们中的一些可以加工成低维形式。在这里，我们报告的一锅法制备，在水-空气界面进行，的金属-有机化合物[Cu 2 I2（TAA）]n（TAA=硫代乙酰胺）的薄膜（下至4 nm）。所示的膜是均匀的超过mm 2的面积，光滑，高度透明，机械鲁棒性和良好的电导体与忆阻行为在低频。这种性质的组合，以及制备所需的两种构建块的工业可用性，证明了它们在未来柔性和透明电子产品中的广泛潜力。
英文摘要：
The future of 2D flexible electronics relies on the preparation of conducting ultrathin films of materials with mechanical robustness and flexibility in a simple but controlled manner. In this respect, metal-organic compounds present advantages over inorganic laminar crystals owing to their structural, chemical and functional diversity. While most metal-organic compounds are usually prepared in bulk, recent work has shown that some of them are processable down to low dimensional forms. Here we report the one-pot preparation, carried out at the water-air interface, of ultrathin (down to 4 nm) films of the metal-organic compound [Cu2I2(TAA)]n (TAA= thioacetamide). The films are shown to be homogenous over mm2 areas, smooth, highly transparent, mechanically robust and good electrical conductors with memristive behavior at low frequencies. This combination of properties, as well as the industrial availability of the two building blocks required for the preparation, demonstrates their wide range potential in future flexible and transparent electronics.
