HCID 836279-Fluorenone hydrazone

Procedure

Symmetrical charge transport materials can be prepared by the following procedure. In the first step a 9-fluorenone or a derivative compound reacts with an excess of hydrazine at 50-70° C. for 1-6 hours to produce a 9-fluorenone hydrazone compound or derivative thereof. Then, the 9-fluorenone hydrazone compound can be isolated and purified. In the next step, the 9-fluorenone hydrazone reacts with a linking compound having 2 aldehyde groups or ketone groups, such as OCH—CHO, a quinone derivative, or a diphenoquinone derivative, in a mole ratio of 2:1 (2 mole of hydrazine derivative with 1 mole of the linking compound). The desired product can be isolated and purified by recrystalization or/and column chromatography.
