Triphenyl groups are aromatic compounds consisting of three fused benzene rings known for their high thermal stability and excellent charge transport properties. They exhibit strong π-π interactions, which facilitate their use in semiconductor materials for efficient charge transport. Triphenyl groups can be functionalized with various electron donating or accepting groups, enabling their use in a wide range of optoelectronic devices. Their high glass transition temperature and chemical stability make them suitable for high-performance semiconductors operating under harsh conditions. Triphenyl groups have found applications in OLEDs, OFETs, and solar cells, helping to improve device efficiency and stability.
