A new fluorenone derivative (L) with optical limiting effect was designed and synthesized. Its structure was characterized by IR, UV, elemental analysis and single crystal X-ray diffraction. The optical limiting property of the compound was tested by Z-scan technique. It shows that the compound exhibits strong two-photon absorption at 532nm. The two-photon absorption cross section of the compound is 396 × 10-46cm4s / photon.
