Dendrimers are a class of polymeric macromol. that are unique in that they have well defined, globular structures with high symmetry and low polydispersity. There has been recent interest in the synthesis of polyphenylene dendrimers due to their well defined, shape persistent architectures. In this study we have synthesized G0 and G1 polyphenylene dendrimers with shape persistent cores via a series of Suzuki cross coupling reactions and conversion of aryl bromides to boronic acid derivatives The dendrimers have been characterized by 1H and 13C NMR spectroscopy, mass spectrometry and elemental analyses. A crystal structure of the G0 methoxy-terminated dendrimer was obtained. We are currently using mol. modeling to investigate dendrimer topol. In conclusion a new set of rigid dendrimers with triphenylbenzene cores were successfully synthesized in high yields. In order to investigate a variety of topologies different cores are being synthesized, for example tetraphenylmethane and hexaphenylbenzene.

3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. Due to the reactivity of bromide, they are used as potential precursors or important intermediates in organic synthesis. Safety of 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl
