The Synthesis and Characterization of Novel Dibenzosulfide Diamine and the Application in the Determination of Heavy Metals

Synthesis and cytotoxicity against tumor cells of pincer N-heterocyclic ligands and their transition metal complexes

“…In 1, a broad band is observed, which presumably originates from the association of molecules though intermolecular hydrogen bonding. 61 …”

Binaphthyl-based macromolecules: a review

“…As a recognition motif, podand based receptors have been reported to be used successfully as recognition components in optical or electrochemical sensors. [105][106][107][108][109] In fact, various macrocyclic compounds, such as crown ethers, cryptands, and calixarenes, have been synthesized and structurally characterized to generate ionophore model systems. In addition to these macrocyclic compounds, podands have also been employed as non-cyclic ionophore models.…”

“…In our previous studies we reported the synthesis of dibenzosulfide and dibenzosulfoxides aza macrocycles as metal cations receptors. 109,142,143 According to the inhibitor effects of some of these macrocycles in biological studies 144 and previously mentioned application of S-BINOL-based podand 3.47 containing amide groups in the determination of Ag + , Hg 2+ , Cr 3+ , Pb 2+ , and Ni 2+ cations, 110 we were encouraged to synthesize various S-BINOL aza macrocycles 3.61-3.67 and carry out the complexation studies. 145 In order to have a clue about the selectivity of the synthesized macrocycles, we also reported the conductance study of complexation of several different metal ions with 3.66 in methanol solution.…”

A convenient synthesis of novel symmetrical bis-Schiff bases of 2, 2'-thio-bis[4-methyl(2-aminophenoxy)phenyl ether] in solution and under solvent-free conditions

“…Compound 1 has been synthesised already and used as a novel complexing agent for Cd +2 and Co +2 with no significant interference from other ions such as Zn +2 being observed. 20 Complexation studies of the Schiff base derivatives of this ligand with heavy metal ions are currently being studied in our laboratory.…”
