The literature on functionalized supramolecules like calix 4]pyrrole, calix 4]resorcinarene and their analytical applications has been comprehensively covered. Various synthetic techniques, mechanism and modifications have also been discussed. When macrocycles interact with other molecules by certain non-covalent interactions such as dipole-dipole, ion-dipole, hydrogen bonding etc, they are termed as supramolecules. This book deals with the comprehensive literature survey on supramolecular chemistry.

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...

In this book, we report the bio synthesis of aqueous stable gold nanoparticles by using Ocimum sanctum leaf extract as both reducing and capping agents. The Ocimum sanctum leaf extract reduced gold nanoparticles (AuNps) were characterized by UV/Vis, particle size analyzer (PSA)and transmission electron mictroscopy (TEM. Additionally, AuNps have been investigated for its application as "Turn Off" fluorescent sensor for Hg II]. A concentration of Hg II] in the limit of 10 M to 10 mM can be detected based on fluorescence quenching of the AuNPs and it was also concluded from the spectroscopic...
