Abstract:

Discotic liquid crystals are a new class of organic electronic materials, and most of these materials display hole-transporting properties. n-Type discotic materials with electro n-transporting properties are rare. Azatriphenylene is one of the most important discotic materials having similar structure to triphenylene derivatives. The introduction of nitrogen atom(s) into the molecular structure of azatriphenylene enhanced its electron affinity properties, making the azatriphenylene derivatives potential n-type organic semiconductors and important materials in terms of their application in optoelectronic devices. This paper reviews recent research progress towards the development of discotic azatriphenylene derivatives, provides discussion on their synthetic methodologies, and accesses their properties as well as their molecular structures such as di-azatriphenylene, tetra-azatriphenylene, and hexa-azatriphenylene. As potential n-type organic semiconductors, the prospective applications of the azatriphenylene materials in optoelectronic devices are explored.

Key words: Discotic liquid crystal, Triphenylene, Aza-material, n-Type organic semiconductor, Optoelectronic device
