Collection: Small Molecule Semiconductor Building Blocks

Small Molecule Semiconductor Building Blocks — gathers aromatic building blocks such as carbazole, fluorene, anthracene, pyrene, and benzothiadiazole, which form the core structures of small-molecule semiconductors. This category includes halogenated derivatives and boronate groups that are ready for further functionalization through coupling reactions.

Small Molecule Semiconductor Building Blocks are used by optoelectronic materials researchers to assemble extended conjugated molecules through cross-coupling reactions such as Suzuki and Buchwald-Hartwig. Bromo and iodo derivatives of carbazole, fluorene, and biphenyl serve as starting points for the synthesis of OLED materials and organic semiconductors, while phenanthroline and substituted pyridines are used as ligands or electron-accepting units in the design of functional molecules.
