Synthesis and characterization of termini azobenzene dendrimer
Journal Title: Iranian Chemical Communication - Year 2013, Vol 1, Issue 1
Abstract
Some organic molecules can be isomerized upon photoirradiation and when accompanied by a change in the visible absorption spectrum, it is called photochromism. Azobenzenes are important part of molecular machines and nanotechnology, Which are This phenomenon is called photoisomerization Azobenzene (azo) chromophores , and have been incorporated into a wide variety of materials and molecular architectures, including polymers, dendrimers, and molecular glasses. We synthesized and characterized the AB2 type polyamidoamine (PAMAM) dendrimers by single active site. PAMAM diazobenzene dendrimer was synthesized and characterized by FTIR and NMR (1H, 13C) and CHN-O Elementary analysis. The simple method can be used for the synthesis of Azobenzene derivative PAMAM dendrimer and other similar compounds.
