Pyrimidines (965)

Pyrimidines are aromatic heterocyclic compounds characterized by a six-membered ring with nitrogen atoms positioned at the 1 and 3 locations. Their diverse electronic properties enable them to act as both electron donors and acceptors in semiconductor materials. Pyrimidines can form robust hydrogen bonds, promoting the self-assembly and crystallization of semiconductor molecules, which improves charge transport. Their functionalizability allows for precise tuning of optical and electronic properties, making them highly suitable for various optoelectronic applications. These compounds have been integrated into small-molecule semiconductors for use in OLEDs, OFETs, and solar cells.
