Induction of Cytokinin-Independent Tobacco Tissues by Substituted Fluorenes
, 1971 Two morphactins and three aminofluorenes initiated the formation of compact tissue nodules in hormone-dependent tobacco callus cultures. These nodules, upon subculture, behaved like partially transformed plant tumors.

Studies on Fluorene Derivatives X
Journal of Synthetic Organic Chemistry, Japan, 1958 2-(4'-Bromobenzoyl) benzoic acid was prepared from phthalic anhydride and bromobenzene, then 3-bromofluorenone was synthesized after passing through several steps. This was converted into 3-bromofluorene-9, 9-dichloride, dechlorination of which yielded 3, 3'-dibromobis (biphenylene) ethylene.
