Dendrimers are well-difined, highly branched, globular macromolecules with a large number of reactive end groups unlike the conventional polymers. Thier fascinating properties have led to many potential use in applications as drug delivery systems, self assembly, sensor, light harvesting molecules, nano reactor, and catalysts. In this study, we present synthesis and properities of wholly aromatic polyamide dendrimers with trifluoromethyl group. The synthesis of dendrimers was accomplished according to divergent and convergent approach, in which two reaction of amidation and nitro displacement were utilized iteratively. Details of the reaction behaviors and physical properties of the polyamide dendrimers will be discussed. |
