Several metal complexes of three different functionalized salen derivatives have been synthesized. The salens differ in terms of the electrostatic character and the location of the charges. The interactions of such complexes with DNA were first investigated in detail by UV-vis absorption titrimetry. It appears that the DNA binding by most of these compounds is primarily due to a combination of ...

Salen ligands and relative metal complexes are widely used in many fields, such as catalysis, sensing, optical electronic materials. The introduction of a wide range substituents different positions, both the salen scaffold diamine bridge, allows tuning chemical, catalytic spectroscopic properties. In this contribution, we report synthesis characterization new ligand Co(II) complex bearing male...

In this work, we revisited the disassembly approach (also known as Zelder's approach) recently proposed for sensing pyrophosphate (PPi) in water and based on decomposition of metal-salen complexes. A systematic study devoted to structural optimization novel class PPi-responsive fluorogenic probes was conducted. Screening eight different vicinal diamines ( i.e. , bridge salen ligand) combined wi...

Bu çalışmada çıkış maddesi olarak siyanür klorür kullanıldı. Siyanür klorür, literatürde verilen metotlardan faydalanılarak asetonlu ortamda farklı klor uçlarından 5-hidroksiizoftalik asit kullanılarak 0 oC bir yönlü (monopodal) 2,4-dikloro-6-(3,5-dikarboksifenoksi)-1,3,5-triazin (MNCHIPA) ve oda sıcaklığında iki (dipodal) 2-kloro-4,6-(2,5-dikarboksifenilfenoksi)-1,3,5-triazin (DPCHIPA) bileşik...

Solvent-free copolymerization of epoxides derived from fatty esters of waste cooking oil with phthalic anhydride using (salen)CrIIICl as catalyst and n-Bu₄NCl/DMAP (tetrabutylammonium chloride/4-(dimethylamino)pyridine) as co-catalysts was carried out for the first time under microwave irradiation, where reaction time was reduced from a number of hours to minutes. The polyesters were obtained w...

In situ immobilization of poly[N-(4-carboxyphenyl)methacrylamide] has been performed on silica gel surface. Infrared (IR) and mass spectroscopies as well as thermogravimetry (TG) analysis have been used to elucidate the structure of immobilized polymer. An adsorption capacity of the synthesized composite towards Cu(II), Pb(II), Mn(II), Fe(III), Co(II), and Ni(II) ions has been estimated. Adsorp...

The complexation reaction between salen (Bis(salicylidene)ethylenediamine) and Cu(II) cations in methanol (MeOH), 2-propanol (2-PrOH), acetonitrile (AN), tetrahydrofuran (THF), and chloroform (CHCl3) as nonaqueous solvents at 25º C has been investigated. The stoichiometry and formation constants of complexes have been determined spectrophotometrically and conductometrically by method of continu...
