In this thesis, poly(amidoamine) dendrimers were prepared by two divergent synthesis methods using methyl acrylate and ethylenediamine on an aminopropyl silica supports. As the first method takes longer time, the second method was introduced for reducing time and energy consumption. In this method tetrabutylammonium bromide is used as useful catalysts for both Michael addition and amidation reactions. Then, each of the dendrimer-grafted silica was used as an organic-inorganic hybrid support for immobilization of the symmetric and neutral pincer ligands. Pincer ligands were introduced on modified supports by reacting functionalized supports with cyanuric chloride and 2-amino-pyridine sequentially. Subsequently, the reaction of each immobilized ligands with copper chloride resulted in formation of copper(II) complexes. Using ICP/OES analysis, the loading of the metal was measured and the product of each step was investigated using FT-IR, ATR-FTIR, SEM, TEM, TGA-DTG and elemental analysis. To determine the growth of branches in each step, the data obtained from thermal analysis was compared with the data obtained from elemental analysis.
