Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Gao, Xiangxiang, once mentioned the application of 1642-81-5, Name is 4-(Chloromethyl)benzoic acid, molecular formula is C8H7ClO2, molecular weight is 170.59, MDL number is MFCD00002568, category is chlorides-buliding-blocks. Now introduce a scientific discovery about this category, Safety of 4-(Chloromethyl)benzoic acid.
Fabrication of large-area and uniform semiconducting thin films of two-dimensional (2D) materials is paramount for the full exploitation of their atomic thicknesses and smooth surfaces in integrated circuits. In addition to elaborate vapor-based synthesis techniques for the wafer-scale growth of 2D films, solution-based approaches for high-quality thin films from the liquid dispersions of 2D flakes, despite underdeveloped, are alternative cost-effective tactics. Here, we present layer-by-layer (LbL) assembly as an effective approach to obtaining scalable semiconducting films of molybdenum disulfide (MoS2) for field-effect transistors (FETs). LbL assembly is achieved by coordinating electrochemically exfoliated MoS2 with cationic poly (diallyldimethylammonium chloride) (PDDA) through electrostatic interactions. The PDDA/MoS2 percolating nanofilms show controlled and self-limited growth on a variety of substrates, and are easily patterned through lift-off processes. Ion gel gated FETs are fabricated on these MoS2 nanofilms, and they show mobilities of 9.8 cm(2).V-1.s(-)1, on/off ratios of 2.1 x 10(5) with operating voltages less than 2 V. The annealing temperature in the fabrication process can be as low as 200 degrees C, thereby permitting the fabrication of flexible FETs on polyethylene terephthalate substrates. The LbL assembly technique holds great promise for the large-scale fabrication of flexible electronics based on solution-processed 2D semiconductors.
