The racemic title host compound ( 1 ) formed homochiral inclusion crystals (conglomerate) of 1 with acetone, while heterochiral inclusion crystals (racemate) were obtained when complexed with ethyl acetate. Upon treatment of the homochiral inclusion crystals of 1 with gaseous acetyl chloride in the solid state, optically active 2,3‐bis(fluorenylidene)succinic anhydride ( 3 ) was obtained in high optical purity.
