Use：: Organic light-emitting diode (OLED) devices have received much attention, because they are expected to be a next generation display and light source, thanks to lightweight and flexible organic materials. Triphenylamine is a propeller-like structural chromophore with a nitrogen atom center. The compound has a large steric hindrance and hyper conjugation electronic effect, which can enhance the stability of the nitrogen atomic radical. Triphenylamine materials also have a high hole mobility due to their unique free radicals nature. Many hole transport materials based on triphenylamine derivatives (TPD) are widely usable,because they are heat-resistant and amorphous.In addition to the TPDs, oxadiazole derivatives (PBD) having an electron transport property, Alq3 as a host material,and blue emissive distylyl derivatives are fundamental materials for amorphous OLED devices. It is used in the manufacture of photographic film. Triphenylamines (TPAs) are highly fluorescent compounds that are efficient to induce cell death upon visible light excitation. Triphenylamine is used in organic light-emitting diode as hole-transporters and as a pharmaceutical intermediate. It is coated on film bases as primary photoconductor.
