The synthesis and characterization of s-Triazine polymer complexes containing epoxy groups

It has been synthesized in this study that s-triazine based monomeric complexes including epoxy groups and their polymeric structures. For this reason, cyanuric chloride (I) has been used as starting material. 5-(4,6-dicholoro-2-1,3,5-triazine-2-ylamino)isophtalic acid coded as "III" has been obtained from the reaction of 5-aminoisophtalic acid II and I at -5 degrees C with sodium bicarbonate in aqua/acetone media. Bis(oxiran-2-ylmethyl)-5-(4,6-dichloro-1,3,5-triazine-2-ylamino)izophtalate coded as "V" was synthesized from the reaction of epichlorohydrin (IV) and III in aqua/acetone media with KOH at 2 degrees C. In aqua/ ethanol media at 60 degrees C, monomeric metal complexes (VI, VII and VIII) were obtained from the reaction of V and/or Mn+2, Co+2 and Ni+2. s-Triazine based polymeric metal complexes (IX-XIV) were obtained from the reaction of the monomeric metal complexes and 3,4-dihydroxybenzaldehyde/o-phenylenediamine in 1,4-diaxane media with DIPEA at 60 degrees C. The structure of ligands, monomers and polymers were characterized using H-1 NMR and C-13 NMR, FTIR, ESI-MS, UV-vis spectrophotometers, TGA and elemental analyses. Metal contents in the prepared monomeric and polymeric complexes were determined by inductively coupled plasma atomic emission spectrophotometer (ICP-AES). Magnetic behaviors of the synthesized novel monomeric and polymeric complexes were also investigated. And, these compounds were determined to be high-spin distorted octahedral Mn(II), distorted octahedral Co(II) and distorted octahedral Ni(II). (C) 2019 Elsevier B.V. All rights reserved.
