WebFeb 21, 2024 · 2. Liquid Crystal Displays. One of the areas where organic transistor usage has gained prominence is in liquid crystal displays (LCDs). The American Chemical Society reports organic semiconductors, specifically small-molecule organic semiconductors, as having good tunability, good performance over various temperatures, and as being low … WebCrystal structure determinations confirmed the presence of one monoanionic carboranylamidinate ligand attached to the metal center in a typical κC, κN-chelating mode. The protonated NHR residue ( 3 : R = Cy; 4 : R = i Pr) is directed away from the metal center and does not contribute to coordinative saturation thereof.
