Four novel salicyloylhydrazone derivatives and their terbium(III) complexes were synthesized and characterized. The thermal analysis results showed that the terbium(III) complexes possessed good thermal stability. The fluorescence research results showed that the terbium(III) complex substituted by phenyl possessed the best fluorescence intensity among them, and its fluorescence quantum yield was also the highest. The exploration of the electrochemical properties indicated that the introduction of electron-donating groups to the ligand can increase the highest occupied molecular orbital (HOMO) energy levels and decrease the oxidation potential of the corresponding terbium(III) complexes. The introduction of electron-withdrawing groups to the ligand can reduce their HOMO energy levels and increase their oxidation potential. The results showed that the terbium(III) complexes are good candidates for luminescent material.

A series of nifuroxazide analogues [(2a-2e)-(10a-10f)] have been synthesized, structurally identified and tested for antimicrobial activity against a panel of bacteria (Gram-positive and Gram-negative) and the yeast-like pathogenic fungus Candida albicans. The most active compound in this series was 4-amino-benzoic acid (5-nitro-furan-2-ylmethylene)-hydrazide (2b) and 2-amino-benzoic acid (5-nitrofuran-2-ylmethylene)-hydrazide (2d). Furthermore, compounds (9a-9g) and (10a-10g) recorded no activity against selected species except compounds (9f) and (10f) suggesting that using furoic hydrazide and the corresponding hydrazide of thiophene did not improve the antimicrobial activities for this type of compounds. Regarding the activity against Candida albicans, all compounds showed no activity with an exception of substituted nitro furan (2a-2d).

Dioxouranium(VI) nitrate complexes with 10 schiff bases obtained by the condensation of furfural and 2-acetylfuran with isonicotinoylhydrazine, benzoylhydrazine, salicyloylhydrazine, anthranilic acid, and 4-aminoantipyrine have been synthesized and characterized on the basis of IR spectra, conductance, magnetic, elemental analyses and molecular weight data.
