Synthesis of Novel Bis-Benzimidazolyl Podands: A new Chemosensor for Cu2+

Some new compounds based on bis-benzimidazole moieties have been synthesized and characterized by IR and NMR spectroscopies. The ability of 3a in transition metal cation sensing such as Co2+, Ni2+, Zn2+, Mn2+, Fe2+ and Cu2+ have been investigated by Uv-vis and fluorescence spectroscopy in methanol solvent. The complexation constants and complex stoichiometry of Cu2+ have been determined. The ex...

Thiacalix[4]arene based reconfigurable molecular switches: set-reset memorized sequential device.

The fluorescent chemosensors 3, 5 and 7 based on thiacalix[4]arene bearing naphthyl groups have been designed and synthesized. The optical chemosensor 3 based on a thiacalix[4]arene of cone conformation behaves as "turn-on" optical chemosensor for Fe(3+) and F(-) ions. However, chemosensors 5 and 7 based on a thiacalix[4]arene of 1,3-alternate conformation demonstrate "turn-on" optical behaviou...

Employing α-Fe2O3 /Mn2P2O7 as a nano photocatalyst for degradation of toluene in aqueous environment

In this study, α-Fe2O3 nano-spheres are immobilized on the surface of manganese pyrophosphate(Mn2P2O7) support using forced hydrolysis and reflux condensation (FHRC) method. The synthesizedα-Fe2O3/Mn2P2O7 were characterized by FTIR, SEM, BET EDX, and XRD. The photocatalytic activity fromα-Fe2O3/Mn2P2O7 was investigated for the removal of toluene in aqueous solution by UV/H2O2 ...
