Description and Uses
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.
