| Hazard Information | Back Directory | [Description]
ICz-Br, namely 2-bromoindolo[3,2,1-jk]carbazole(1174032-81-5), has a fully planarized arylamine building block which could be weakly electron accepting or electron donating. It is an OLED intermediate that has been commonly used in the design of efficient blue thermally activated delayed fluorescent (TADF) emitters and bipolar host materials.
| [Uses]
2-Bromoindolo[3,2,1-jk]carbazole(1174032-81-5) has a fully planarised arylamine structural unit which can be weakly electron accepting or electron donating. It can be used as a host material for newly developed materials to prepare highly efficient organic light-emitting diodes.
| [Synthesis]
Dissolve indole [3,2,1-jk] carbazole (2.40 g, 10 mmol) and chloroform (20 mL) in a 100 mL single-necked flask and place in ice water. Then, N-bromosuccinimide (NBS, 1.96 g, 11 mmol) was added in portions and reacted at room temperature overnight. Anti-Upon completion, the reaction solution was extracted three times with dichloromethane (DCM) and washed three times with water, dried over anhydrous sodium sulfate, and filtered and spun dry. Use 200-300 mesh silica gel for column chromatography, and select eluent petroleum ether / DCM. The product ratio is 5: 1 to obtain 3.04 g of white solid 2-broMoindolo[3,2,1-jk]carbazole with a yield of 95%. |
