Specifications | MSDS | Literature and Reviews
2,7-dibromocarbazole (CAS number 136630-39-2), also known as 2,7-dibromo-9H-carbazole, is a building block for the synthesis of small molecules of carbazole series or carbazole back-boned polymers in the application of OFETs, OLEDs, PLEDs and OPVs.
Carbazole derivatives, small molecules or poly(2,7-carbazole)s, have been one of the most popular candidates for the application of organic electronics due to their well-known good electron-donating abilities and chemical stability comparing with fluorene units. Also, the functional group on the 9-position makes them chemically available to be easily adjustable to different aromatic or alkyl chains to allow solubility for devices film morphology or even further tuning the energy levels of such compounds.
One of the most popular products made available from 2,7-dibromocarbazole is PCDTBT, a well-known polymer semiconductor used for polymer solar cells. A good example for adjusting the solubility of the carbazole compounds by using 2,7-dibromocarbazole as the starting materials is the synthesis of 2,7-dibromo-9-heptadecanylcarbazole.
