What is 2,7-Dibromocarbazole?
Description
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.
What are the applications of 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.
