2,7-Dibromo-9H-carbazole(Cas 136630-39-2) Usage

Application

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.

Description

2,7-Dibromocarbazole (2,7-DBCZ) is one of the most frequently detected polyhalogenated carbazoles (PHCZs) in the environmental media. 2,7-dibromocarbazole, 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.
