Liquid–liquid extraction of transition metal cations by nine new azo derivatives calix[n]arene
Liquid–liquid extraction of various alkali, alkaline-earth, and transition metal cations with o-(4-hydroxydiazophenyldiazophenyl)-p-tert-butylphenol (L1), bisdiazo… Expand
Synthesis and characteristics of poly(3-pyrrol-1-ylpropanoic acid) (PPyAA)–Fe3O4 nanocomposite
Poly(3-pyrrol-1-ylpropanoic acid) (PPyAA)-Fe(3)O(4) nanocomposite was successfully synthesized by an in situ polymerization of 1-(2-carboxyethyl) pyrrole in the presence of synthesized Fe(3)O(4) na… Expand
A versatile approach toward chemosensor for Hg2+ based on para-substituted phenylazocalixarene containing mono ethyl ester unit
Abstract In the present study, six new azocalixarenes have been synthesized by reacting calixarene with p -substituted aniline and ethyl bromoacetate. Characterization of these compounds has… Expand
Synthesis and structural characterization of bisazocalixarene with melamine: Metal ion extraction studies
Abstract In this study, the synthesis and characterization of novel bisazocalixarene [2-amino-4,6-bis(5-azo-25,26,27-tribenzoyloxy-28-hydroxycalixarene)-1,3,5-triazine] ( 5 ), symmetrically… Expand

Azocalixarenes, which have a conjugated chromophore azo (–N=N–) group in p-positions, are synthesized in “one-pot” procedures in satisfactory yields. Their structures in the solid and solution are… Expand
The synthesis of some new derivatives of calixarene containing azo groups
Abstract Five new compounds p-(4-n-butyl-phenylazo)calixarene ( 1 ), p-(4-phenylazophenylazo)calixarene ( 2 ), p-(4-acetanilidazo)calixarene ( 3 ),… Expand
Comparative studies on the solvent extraction of transition metal cations by calixarene, phenol and ester derivatives.
It was found that, all the compounds (L1-L9) examined showed selectivity for transition metal cations such as Ag+, Hg+ Hg2+, and poor efficiency for alkaliMetal cations (Na+ and K+). Expand
LIQUID-LIQUID EXTRACTION OF TRANSITION METAL CATIONS BY CALIXARENE-BASED CYCLIC LIGANDS
ABSTRACT The selective liquid-liquid extraction of various alkali and transition metal cations from the aqueous phase to the organic phase was carried out by using p-tert-butylcalixarene (L1),… Expand
Transition metal cations extraction by ester and ketone derivatives of chromogenic azocalixarenes.
The main aim is to prepare new chromogenic azocalix[n]arene molecules to elaborate an extractant with high extractant selectivity for metal ions able to detect this type of pollutant. Expand
