—Trifluoromethyl Radicals Tune Up Organic Electronics “One-step, solvent-free, catalyst-free method adds trifluoromethyl groups to polycyclic aromatic hydrocarbons to enhance organic semiconductors” Organic-based materials are increasingly being used to replace silicon- and metal-based components in optoelectronic devices—the organic materials are typically lighter weight, more flexible, and lower in cost. Scientists have recognized that strong electron-withdrawing groups such as trifluoromethyl enhance the electronic properties and improve the stability of the organic materials, which include polycyclic aromatic hydrocarbons (PAHs). But so far, none of the synthetic routes to add CF3 groups to PAHs is optimal.
