| Summary: | This thesis examined two distinct characteristics of lanthanide and transition metal complexes: Magnetism and Luminescence. In chapter two, synthesis, characterization, magnetic and luminescence investigations of mononuclear lanthanide complexes using Schiff-base tetrazine based ligand were performed. Six novel lanthanide complexes, [LaIIICl3(Htzpy)2], [TbIIICl2(Htzpy)2(MeOH)]Cl, [HoIIICl2(Htzpy)2(MeOH)]Cl, [DyIIICl2(Htzpy)2(MeOH)]Cl, [ErIIICl2(Htzpy)2(MeOH)]Cl and [YbIIICl2(Htzpy)2]Cl have been synthesized successfully and the studies were performed with the application of single crystal X-ray diffractometry, SQUID magnetometry, UV-Vis-NIR spectrometry and custom-built hyperspectral microscope (for luminescence spectroscopy). Chapter three is mainly about the luminescence properties of CoII and CuII complexes using a naphthalimide based ligand. Two complexes, [CoIICl2(Pynap)2] and [CuIIBr2(Pynap)2] were synthesized successfully and characterized using single crystal X-ray diffractometry, UV-Vis spectrometry and hyperspectral microscope (for luminescence spectroscopy). In order to have information about the electrochemical properties of CoII and CuII complexes, their redox activity was monitored by cyclic voltammetry (CV) and compared with the parent ligand. In addition, a rational design to synthesize a new ligand (dipicnap) which consists of both naphthalimide and dipicolinic acid moieties is presented. |
