4-BROMO-P-TERPHENYL

4-BROMO-P-TERPHENYL (CAS: 1762-84-1), also named 4-bromo-1,1':4',1''-terphenyl, is a rigid linear conjugated aromatic compound with a straight-chain para-terphenyl skeleton and a single bromine atom substituted at the terminal benzene ring. It features high thermal stability, excellent π-π conjugation effect and good film-forming property. The reactive aryl bromide bond provides stable active sites for palladium-catalyzed cross-coupling reactions, while the long linear terphenyl structure endows outstanding optoelectronic transmission performance. This product is soluble in hot toluene, xylene, THF and other aromatic organic solvents, poorly soluble in alcohols, and insoluble in water. It is a classic high-purity organic building block widely used in OLED luminescent materials, organic semiconductor synthesis and custom aromatic derivatization.

1. OLED Organic Light-Emitting Material Intermediate: 4-BROMO-P-TERPHENYL (CAS: 1762-84-1) is a core precursor for synthesizing blue light-emitting host materials and electron transport materials for OLED devices. Its linear rigid terphenyl structure reduces molecular intermolecular stacking, improves material thermal stability and luminous efficiency, and effectively prevents device exciton quenching to extend OLED service life. 2. Organic Semiconductor Material Building Block: This linear conjugated monomer can be used to construct high-mobility organic semiconductor molecules and organic field-effect transistor (OFET) materials. The regular straight aromatic chain optimizes molecular arrangement and carrier transmission efficiency in thin-film devices. 3. Palladium-Catalyzed Cross-Coupling Reactions: The terminal reactive C-Br bond supports Suzuki coupling, Heck reaction, Sonogashira coupling and Buchwald-Hartwig amination. It is widely adopted to synthesize multi-extended conjugated aromatic molecules for advanced optoelectronic material customization. 4. Laboratory Organic Conjugation Chemistry Research Reagent: High-purity electronic-grade 4-BROMO-P-TERPHENYL (CAS: 1762-84-1) is used for academic research on linear conjugated molecular structure-activity relationship, supramolecular self-assembly and photophysical property testing in university chemistry labs and optoelectronic R&D institutes.
