Truxene is a polycyclic aromatic hydrocarbon. The molecule can be thought of as being made up of three fluorene units arranged symmetrically and sharing a common central benzene. Truxene is solid, and it is slightly soluble in water.

==History== Truxene has been known since the end of the 19th century. J. Hausmann came across it in 1889 while investigating the reactions of 3-phenylpropionic acid with phosphorus pentoxide. He could not determine the exact structure but assumed it was a cyclic trimer of 1-indanone. According to him, it was formed by the condensation of 1-indanone resulting from intramolecular acylation of 3-phenylpropanoic acid.
