A series of novel Knoevenagel products of 2-nitrofluorene to a series of aromatic aldehydes were obtained in the presence of sodium hydroxide under microwave irradiation (500 W) within short reaction times (5～8 min) in high yields (78%～89%). The structures of the products were characterized by IR, ¹H NMR, MS techniques and elemental analysis. The UV absorption and fluorescent spectra of compounds 3a～3d were detected and showed that they had fluorescence.

Key words: 2-nitrofluorene, Knoevenagel, microwave-assisted, fluorescent property, UV absorption
