Specifications | MSDS | Literature and Reviews

3,6-Dibromo-9-(2-ethylhexyl)-9H-carbazole (CAS number 173063-52-0) is a carbazole derivative bearing two bromide groups at 3 and 6-positions as well as a 2-ethylhexyl group at the 9-position. The bromo-substituents enable 3,6-dbromo-9-(2-ethylhexyl)-9H-carbazole to undergo facile reactions, including Suzuki coupling reactions and Kumada polymerisation. A carbazole copolymer, linked at the position 2,7 and 3,6, is synthesised by combining 3,6-dibromo-9-(2-ethylhexyl)-9H-carbazole with 2,7-dipinacol-(2-ethylhexyl)-9H-carbazole. The resulting carbazole copolymer possesses a wide band gap of 3.2 eV and displays a narrow emission band at 400 nm (with a full width half maximum of 56 nm).

Synthetic monomer for HTL materials (in OPVs and OLEDs)

A novel copolymer of fluorene and carbazole, known as PF8Cz (poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-(9-(2-ethylhexyl)-carbazole-3,6-diyl)]) can be prepared from 3,6-dibromo-9-(2-ethylhexyl)-9H-carbazole and 2,2'-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane). PF8Cz has an optical bandgap of 3.06 eV, widely used as a hole-transport layer (HTL) material in OLEDs.
