Abstract

In this paper, two basic mid-products were obtained by reacting cyanuric chloride and hydroquinone or 1,4-phenylendiamine, respectively. EBA1 and EBA2 were obtained from the reaction of these compounds and 4-hydroxybenzaldehyde. Four target ligands encoded as EBL1-EBL4 were obtained by reacting these compounds with 4-aminobenzoic acid and 5-aminoisophthalic acid, respectively. These obtained ligands were characterized by FTIR, elemental analysis, 1H and 13C NMR and methods. The obtained target ligands were reacted with [M(Salen/Saloph)]2O (M= Cr3+ and Fe3+) to obtain [M(Salen/Saloph)] capped complexes. These complexes were characterized using elemental analysis, and FTIR. The magnetic properties of the complexes were investigated. The thermal endurance of the complexes was determined using the TGA technique. At the end of the study, 6 tetrapodal ligands and 16 tetrapodal complexes, which are thermally stable with paramagnetic properties, were synthesized and characterized.

Abstract

Bu çalışmada ilk olarak sırasıyla siyanürik klorür ve hidrokinon veya 1,4-fenilendiaminin reaksiyona sokulmasıyla iki bazik ara ürün elde edildi. Bu bileşiklerin 4-hidroksibenzaldehit ile reaksiyonundan EBA1 ve EBA2 elde edildi. Bu bileşiklerin sırasıyla 4-aminobenzoik asit ve 5-aminoizoftalik asit ile reaksiyona sokulmasıyla EBL1-EBL4 olarak kodlanan dört hedef ligand elde edildi. Elde edilen bu ligandlar, FTIR, elementel analiz, 1H ve 13C NMR yöntemleriyle karakterize edildi. Elde edilen hedef ligandların [M(Salen/Saloph)]2O (M= Cr3+ ve Fe3+) ile reaksiyonu sonucu [M(Salen/Saloph)] başlıklı kompleksler elde edildi. Bu kompleksler elementel analiz ve FTIR kullanılarak karakterize edildi. Komplekslerin manyetik özellikleri araştırıldı. Komplekslerin termal dayanıklılığı TGA tekniği kullanılarak belirlendi. Çalışmanın sonunda termal olarak kararlı ve paramanyetik özelliklere sahip 6 adet tetrapodal ligand ve 16 adet tetrapodal kompleks sentezlenmiş ve karakterize edilmiştir.
