Özet

We aimed to synthesize and characterize novel salen/salophen capped polymeric complexes including oxirane groups. For this purpose, we used 2,4,6-trichloro-1,3,5-triazine (I) as starting material. 2,4-dichloro,6-(3,4-dihydroxyphenylethylamino)-1,3,5-triazine (II) was synthesized by the reaction of an equivalent (I) and an equivalent dopamine. 2-(3,4-bis(oxiran-2-ylmethoxy)phenethyl)amine,4,6-dichloro-1,3,5-triazin (III) was synthesized by the reaction of two equivalents of epichlorohydrin and an equivalent of (II). [(Salen/Salophen) (Cr(III)/Fe(III))] capped complexes of (III) were synthesized by reaction of the reactants, codded as IV, V, VI and VII. Then, these monomeric complexes were polymerized by using ethylenediamine and o-phenylenediamine in 1,4-dioxane media, codded as VIII, IX, X, XI, XII, XIII, XIV and XV. II and III, monomeric and polymeric complexes were characterized by means of elemental analyses, H-1-NMR (spectrometry) and C-13-NMR (spectrometry), FT-IR spectrometry, ESI-MS and thermal analyses. Metal content in the prepared polymeric complexes was determined by inductively coupled plasma atomic emission spectrophotometer (ICPAES). We also synthesized novel polymeric complexes and investigated their effects on magnetic behaviors of [Cr(III)/Fe(III)(salen/salophen)] capped complexes. The complexes were determined to be low-spin distorted octahedral Fe(III) and distorted octahedral Cr(III).
