Conductance Studies on Complex Formation between c-Methylcalix[4]resorcinarene and Titanium (III) in Acetonitrile-H2O Binary Solutions

Abstract

Received: 25 April 2013; in revised form: 8 May 2013 / Accepted: 10 May 2013 / Published: 27 September 2013 Abstract: Calixresorcinarenes have proved to be unique molecules for molecular recognition via hydrogen bonding, hydrophobic and ionic interactions with suitable substrates such as cations. The study of the interactions involved in the complexation of different cations with calixresorcinarenes in solvent mixtures is important for a better understanding of the mechanism of biological transport, molecular recognition, and other analytical applications. This article summarizes different aspects of the complexes of the Ti

Analysis of complexation between new bidentate bis-NHC ligand and some metal cations at different temperature

“…To determine the stability, selectivity and stoichiometry of NHCL-M n+ complexes with different metal cations, the conductometric technique was chosen [26]. This technique has several advantages such as great sensitivity [27], low cost [28] as well as simple experimental arrangement [29] compared with other techniques such as spectrophotometry, calorimetry [30], and NMR spectroscopy [31], and potentiometry [32][33][34][35]. The sensors based on electrochemical methods have been used to measure the analyte concentrations in water samples.…”

A Novel Potentiometric Sensor Based on 1,2-Bis(N’-benzoylthioureido)benzene and Reduced Graphene Oxide for Determination of Lead (II) Cation in Raw Milk

“…During the last decade, the potentiometric and voltammetric sensors based on ionophores with high selectivity for specific metal ions have been developed to detect respective metal ions [5][6][7][8][9][10][11]. Heavy metal ions with consanguineous attraction connection and soft coordination center such as N, S, Se, and P have been reported; therefore, the functional groups containing N, S, Se, and P atoms in thioether, thiaayloxy, arylthiaalkoxy, pyridyl and benzothiazoyl groups would significantly improve the selectivity of ionophore to the heavy metal ion [12][13][14][15][16][17].…”
