A new series of calix 4]pyrrole derivatives bearing azo-moiety at the mesoposition of the macrocycles have demonstrated the ability for liquid-liquid extraction, preconcentration and transport of Th(IV) across a liquid membrane. Various significant extraction parameters such as effect of pH, effect of solvent and effect of reagent concentration were investigated, which showed high affinity and selectivity towards Th(IV) in the presence of large quantities of associated metal ions. The wavelengths of maximum extraction ( max) and molar absorptivity ( ) have also been determined. The...

Various novel substituted acetyl salicylanilide derivatives were prepared and Characterized all the analytical and spectroscopic data and support the proposed structures. All the seven compounds were scanned against microorganism for their antibacterial activity like Escherichia coil, Pseudomonas putida, Bacillus cereus, Pseudomonas aeruginosa, Staphylococcus aureus and for Antifungal activity of above produce compounds ware scanned against different fungus like Alternative rock, Aspergillus nigar, Rhizoctonia solani. Among them, 2-(4-Sulfamoyl phenylcarbamoyl) phenyl acetate 2-(4(N-(5...

The FTIR spectroscopy of charge transfer complexes of hormones, enzymes, enniatin B and beuvericin are studied here. The FTIR spectra of CTCs of hormones namely insulin, thyrotropin-releasing hormone, vasopressin and glucagon with organic acceptors is the subject of present study. It is found that these hormones are small band gap semiconductors except glucagon. The CTCs of these hormones with standard organic acceptors such as TCNQ, TCNE, DDQ, chloranil and iodine or KI-I2 are semiconductors having two band transports. Some of them are Peierls semiconductors while others have non-universal...
