PROBLEM TO BE SOLVED: To provide a halogenated arylidenefluorene derivative useful as a production intermediate for synthesizing a π-conjugated polymer for organic electronics.
SOLUTION: A phosphorus-containing fluorene compound is reacted with a carbonyl compound to thereby synthesize the halogenated arylidenefluorene derivative in which the conjugation is extended. The resultant dihalogeno intermediate is used as the production intermediate for the π-conjugated polymer.
