Abstract

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 homogeneous 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.
