Abstract
Dithiocabamates are valuable compounds due to their wide application as herbicides, fungicides, antitumor and etc. Another aspect of dithiocarbamates is their application in coordination chemistry. In this project, 3-((pyridin-2-yl) methyl amino) propane nitrile was prepared via Michael addition reaction of 1-methyl¬amino¬pyridine and acrylonitrile in water. Then this compound was converted to its potassium dithiocarbamate salt via treatment with carbon disulfide in the presence of potassium hydroxide in tetrahydrofuran. The prepared ligand was used in complexation with metal salts of Zn, Hg, Ni and Sn to prepare their dithiocarbamate complexes. The structure of complexes was elucidated by...
Design and Synthesis of the Late Transition Metal Complexes Based on Naphthalimide and Pyridine Ligands and Study of their Photophysical Properties

Abstract
In the first project, we have described the preparation of quadruply linked naphthalimide compounds 3-6. These compounds showed weak and strong excimeric emissions in solid and solution states, respectively. The experimental and theoretical results showed that the adjacent naphthalimide rings were oriented in solution so that intramolecular interchromophoric interactions enhanced the quantum yield efficiencies. However, although the strong intramolecular π and solute-solvent interactions in solution were replaced by n→π*, inter- and intramolecular π-interactions in the solid state, the naphthalimide units were aligned so that the quantum yield efficiencies were diminished. Also, a rise in...
