Abstract

In this study, the complex of [Cu(4-Cl-phenac)2(ina)2] (4-Cl-phenac = 4 chlorophenylacetate; ina = isonicotinamide) with general formula was synthesized. Elemental analysis and FT-IR spectroscopy methods were used to determine the structure of the complex and thermal stability of the complex was examined by TGA/DTA analysis. Optical properties and fluorescence behavior of the complex were investigated by UV-Vis and Fluorescence Spectroscopy. In these complexes copper ions possess an tetrahedral geometry with two oxygen atoms of 4-chlorophenylacetate anions, two nitrogen atoms from two isonicotinamide. The anhydrous complex beganto decompose at about 200 °C. As a result of the remove of organic ligands from the structure, CuO was a final product of thermal decomposition. The anhydrous complex began to decompose at about 200 °C. When the complex was excited at a wavelength of 225 nm, the emission peaks were observed between 350-475 nm.

Özet

Bu çalışmada [Cu(4-Cl-phenac)2(ina)2] genel formüllü (4-Cl-phenac=4-klorofenilasetat; ina=izonikotinamid) kompleks sentezlenmiştir. Kompleksin yapısını aydınlatmak için elementel analiz, FT-IR spektroskopisi yöntemleri kullanılmış ve kompleksin termal kararlılığı TGA/DTA analizi ile incelenmiştir. Kompleksin optik özellikleri ve floresans davranışları UV-Vis and Floresans Spektroskopisi yöntemleri ile incelenmiştir. Bakır atomları çevresinde karboksilat oksijen atomları üzerinden koordine olan 4-klorofenilasetik asit anyonları ve piridin halkasında bulunan azot atomu üzerinden koordine olan izonikotinamid ligandları ile hafif bozulmuş tetrahedral geometri oluşmaktadır. Susuz kompleks yaklaşık 200°C’den itibaren bozunmaya başlamaktadır. Organik ligandların da yapıdan parçalanarak uzaklaşması neticesinde komplekslerden geriye CuO kaldığı belirlenmiştir. Kompleks 225 nm dalga boyunda uyarıldığında yaklaşık 350 – 475 nm arasındaki bölgede ışıma yaptığı gözlemlenmiştir.
