Synthesis of N-(Nitrofluorenylidene)anilines and their Application as Electron Transport Materials in Positive Charge Electrophotography
N-(Nitrofluorenylidene)anilines were synthesized by the condensation of nitrofluorenones with substituted anilines in the presence of zinc chloride. 2-Methyl, 2-ethyl, 2-isopropyl and 2-trifluoromethyl derivatives from 2,4,7-trinitrofluorenone showed high
