Collection: Biphenyls [Small Molecule Semiconductor Building Blocks]

Biphenyls [Small Molecule Semiconductor Building Blocks] — a collection of halogenated and boronated biphenyl derivatives, such as iodo and bromo derivatives, as well as boronate esters (pinacol and neopentyl glycol), that form a two-ring conjugated aromatic framework. This biphenyl structure serves as the basic unit for building longer pi-conjugated systems through carbon-carbon coupling reactions.

Halogenated biphenyls and their boronic acid/ester derivatives are widely used in cross-coupling reactions such as Suzuki-Miyaura and Negishi to assemble small molecule organic semiconductors, OLED materials, and liquid crystals. Researchers in electronic materials and synthetic organic chemistry utilize iodo, bromo, or boronate groups with different reactivities to build structures stepwise and in a targeted manner.

Example products in this collection: TCI I0785 1591-31-7 4-Iodobiphenyl, TCI B5703 398128-09-1 2,2'-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,1'-biphenyl, TCI B5321 187275-73-6 3-Bromo-4'-iodo-1,1'-biphenyl, TCI B5704 850264-92-5 3,3'-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,1'-biphenyl, TCI B4166 207611-87-8 4,4'-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)biphenyl, TCI B5759 844856-42-4 3-Bromo-3'-chloro-1,1'-biphenyl, TCI B3648 105946-82-5 4-Bromo-4'-iodobiphenyl, TCI B5764 164334-69-4 3-Bromo-4'-chloro-1,1'-biphenyl.

Pay attention to the substitution position (para, meta) and the combination of halogen and boronate groups on a single molecule, as these affect the selectivity of stepwise coupling reactions, as well as the storage conditions of boronate esters, which are sensitive to moisture. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
