Abstract: In this paper, we report on our ongoing progress on the synthesis and study of branched molecular architectures with a conjugated scaffold. Specifically, new conjugated dendrons incorporating 1,2,4-triethynyl-phenyl units have been developed and used as building blocks for the synthesis of isomeric branched conjugated systems and light-harvesting dendrimers.
Keywords: dendrimers; alkynes; cross-coupling; fullerenes; conjugation.
