L-Glutamic acid-based novel dendritic phenylacetylene derivatives 1 and 2 were synthesized and polymerized with a rhodium catalyst to afford the corresponding polymers [poly(1) and poly(2)] with ...

Synthesis of monomers. The synthesis of phthalimide dialkyne monomers is shown in Scheme 1.The dialkyne monomers, namely, BAPPE, BAPPEBPA and BAPPK with phenylacetylene endcapping, were ...

Carbon nanostructures seen in circumstellar envelopes surrounding carbon—rich stars could have a chemical origin with soot particles created during fuel burning.
