Synthesis Nano Dendrimer Supramolecular with Melamine Core

摘要

Dendrimers are a family of three-dimensional polymers and in nano dimension which are characterized by spherical structure. Excellent structural properties of dendrimers have distinguished them completely from linear polymers. Dendrimers have monodispersity characteristic and their size and molecular weight is controllable exactly during synthesis such as PAMAM dendrimers. Melamine can be used for synthetic core dendrimer through various methods including divergent. Melamine and related derivatives are able to form self-assembling compound via organized intramolecular networks of hydrogen bonds and provide useful molecular scaffolding components which are exploited by the field of supramolecular chemistry; which is beyond covalent bonding. In this study, the dendrimers of generated 0.5 and 1 with ester and primary amine-terminated groups with melamine and methyl acrylate were synthesized. The Synthesized dendrimer is able to form hydrogen bonding due to its nitrogen, oxygen and hydrogen atoms which was led to supramolecule characteristic. The reaction products were identified with H NMR, and ~(13)C NMR, FT-IR, MASS spectroscopic techniques. Also nano properties of the supramoleculs were determined by X-ray diffraction method. Supramolecular characteristics of synthesized dendrimer can be studied by shifts in H-NMR peaks and also flattening of FT-IR spectrum. The synthesized dendrimer derivatives are promising for environmental and medical applications. Also, such compounds might be reacting with transition metals as ligand and could be served as catalysts.
