A new fluorogenic calix[4]arene has been synthesized by reacting acid chloride of fluorescein and partially reduced nitrocalix[4]arene. The synthesized compound is characterised by UV, NMR and mass spectra. Fluorescence characteristics of N,N'-(fluorescein)-7,19-dinitro-25,26,27,28-tetrahydroxy-1.13 calix[4]aryl hydroxamic acid have been investigated in methanol, chloroform, toulene and dioxane and tested for lasing performance. Relative output, lasing wavelength and laser yield of the compound are reported. The dependence of solvent polarity on its lasing properties are discussed.
