Multinanometer long phenylacetylene-end-capped poly(triacetylene) (PTA) oligomers with dendritic side chains of generation one to three have been prepared; UV–VIS measurements indicate that there is no loss of π-electron conjugation along the PTA backbone in the higher generation compounds despite distortion from planarity due to the bulky dendritic wedges.
