N-Phenyl-3-biphenylamine TCI P1497

N-Phenyl-3-biphenylamine (TCI product code P1497) is a secondary diarylamine. Its nitrogen atom carries one phenyl group and one biphenyl group attached at the meta position (3-biphenylyl). TCI classifies it as a small molecule semiconductor building block for research in organic electronics. In the laboratory, its N-H bond serves as the coupling site for building triarylamines. Triarylamines are a very important class of compounds and are widely used as hole-transport materials in OLEDs, perovskite solar cells and photoconductive devices.

Researchers choose this material because it combines an electron-rich diarylamine nitrogen with a biphenyl unit linked at the meta position. A meta linkage usually limits conjugation length more than a para linkage does. This helps keep a wider energy gap and a higher triplet energy in the final material, which matters when designing host and hole-transport compounds. The molecule's non-linear shape can also help stop thin films from crystallising, so a stable amorphous film morphology is easier to achieve. These features make it a practical starting point for building functional organic semiconductors with controlled properties.

In Indonesia, this building block suits functional-materials research groups at universities and research institutions. These groups work on OLEDs, next-generation solar cells and organic sensors. In these laboratories, N-Phenyl-3-biphenylamine is typically used as an intermediate in multi-step synthesis. It is coupled with aryl halides to give new triarylamine structures, which are then purified and characterised before being tested in thin-film devices. It also supports student and postgraduate projects on how linkage position and molecular shape affect the energy levels and film-forming behaviour of organic electronic materials.

• Triarylamine synthesis: the reactive N-H bond is a ready coupling site with aryl halides, so researchers can build triarylamine cores step by step.
• Hole-transport materials for OLEDs: the electron-rich diarylamine nitrogen makes it a good precursor for compounds that carry positive charge through the layers of organic light-emitting devices.
• Perovskite solar cell research: triarylamines made from this building block can be studied as hole-transport layers that move charge from the perovskite absorber to the electrode.
• Host materials with high triplet energy: the meta-linked biphenyl limits conjugation, which helps keep the wider energy gap and higher triplet energy that host materials in phosphorescent devices need.
• Amorphous thin-film studies: the non-linear molecular shape helps suppress crystallisation, so it is useful for investigating stable amorphous film morphology in photoconductive and organic sensor devices.

• Chemical class: secondary diarylamine (N-phenyl, 3-biphenylyl)

Keep N-Phenyl-3-biphenylamine in its original tightly closed container, labelled clearly, in a cool, dry and well-ventilated place. Keep it away from direct light, heat sources and strong oxidising agents, because arylamines can slowly degrade or discolour when exposed to air and light. Once the container has been opened, reseal it promptly. For sensitive device work, consider storing it under an inert atmosphere. When handling the material, wear standard laboratory protective equipment, including gloves, safety glasses and a lab coat, and work in a fume hood to avoid inhaling dust. Do not let it touch your skin or eyes. Always check the TCI Safety Data Sheet for the specific storage temperature, hazard classification and disposal requirements before use.
