9,9-Dimethylfluorene Chemical Properties,Usage,Production

Definition

9,9-Dimethylfluorene is an organic electroluminescent material intermediate. The fluorene derivative is a kind of organic electroluminescent material commercialized at present, wherein 9, 9-dimethyl fluorene is an essential intermediate for synthesizing OLED material.

Synthesis

The method comprises taking dimethyl carbonate as a methylating agent under alkaline substances and reacting with fluorene in an organic solvent system within a certain temperature range to prepare the 9,9-Dimethylfluorene. The method uses dimethyl carbonate as a methylating agent so that the reaction process is stabilized and the economy is greatly improved; meanwhile, the use of dimethyl carbonate avoids the use of low-boiling-point hypertoxic such as methyl iodide, methyl bromide, and the like, is environment-friendly, and the generated wastewater has single component and is convenient to treat.
