Uses |
2,7-Dibromo-9,9′-spirobifluorene can be used in the preparation of 9,9′-spirobifluorene-based small molecules, which can further be utilized as host materials in organic light emitting diodes (OLEDs). |
|
General Description |
2,7-Dibromo-9,9′-spirobifluorene is a 9,9 substituted poly(2,7-fluorene) that is synthesized from 2,7-dribromo-9-fluorenone by reacting with a Grignard reagent of 2-bromobiphenyl. It has high photoluminescence and electroluminescent quantum efficiency that make it useful in the development of organic electronic devices. |
