, p. 279 - 292 (2001)
The synthesis and transition temperatures of a series of novel thienyl-pyrimidine liquid crystalline materials is described. Palladium catalysed coupling of 5-n-alkyl-2-tri-n-butylstannyl thiophenes to 5-bromo-2-iodopyrimidine is used to create novel pyrimidine compounds which exhibit lower melting points than similar pyrimidine liquid crystals. These compounds exhibit a variety of phases including smectic A, C, G, B and hexstatic B also they exhibit several as yet unidentifiable phases. Speculation as to hydrogen bonding in the liquid crystalline core is also discussed therein.

Paragraph 0150-0153, (2019/09/04)
The present invention relates to an organic compound in which a bipyrimidine moiety serving as an electron acceptor is connected via an aromatic linker to a hetero-aromatic moiety serving as an electron donor and containing one to two nitrogen atoms. The organic compound, since it contains both electron donor and electron acceptor moieties in a single molecule, allows electric charges to move easily, thereby increasing luminance efficiency. Also, since the electron donor is made of solid condensed aromatic rings, such as carbazole, acridine, or indole rings, the 3D structure of the molecule is hindered. Thus, the organic compound of the present invention may be used as a delayed fluorescence dopant emitting a blue light of high chromatic purity. The organic compound of the present invention may be applied to organic light-emitting devices, such as an organic light-emitting diode, a display device, and a lighting device, to lower the driving voltage thereof while increasing luminance efficiency and chromatic purity thereof.COPYRIGHT KIPO 2019
