2,6-Diphenylaniline丨CAS 87666-57-7

1. Organic Electronics and OLEDs

Widely used as a hole-transporting material (HTM) or intermediate in the design of:

OLEDs (Organic Light-Emitting Diodes)

Organic photovoltaic devices (OPVs)

Perovskite solar cells

Its planar and rigid structure promotes π-conjugation, aiding charge mobility.

2. Ligand and Intermediate in Coordination Chemistry

Serves as a building block for Schiff base ligands and coordination compounds used in:

Catalysis

Metal–organic frameworks (MOFs)

Sensors

3. High-Performance Polymers

Acts as a monomer or crosslinker in the synthesis of:

Polyimides

Aromatic polyamides

These materials are valued for thermal stability, chemical resistance, and mechanical strength in aerospace and electronics.

4. Pharmaceutical and Agrochemical Intermediate

Although not typically bioactive on its own, 2,6-diphenylaniline is used as an intermediate in the synthesis of:

Kinase inhibitors

Anti-inflammatory agents

Herbicides or fungicides

1. Enhanced Thermal and Chemical Stability

Aromatic substitution at ortho-positions protects the amino group from oxidation and decomposition.

Makes it ideal for high-temperature applications like OLED devices and engineering plastics.

2. Rigidity and Planarity

The structural configuration leads to rigid molecular packing and extended π-conjugation, which improves:

Charge transport

Film-forming properties

Electronic interaction with semiconductors

3. Synthetic Versatility

The amino group allows for:

N-alkylation or acylation

Formation of azo compounds, imines, or amides

Phenyl groups can undergo further functionalization such as halogenation or cross-coupling.

4. Optoelectronic Tunability

Its electronic properties can be tuned by modifying the substituents on the phenyl rings, enabling tailored material design for specific optoelectronic applications.
