p-Conjugated polymers have received much attention because of their semiconducting properties. Synthesis of a variety of p-conjugated polymers were achieved by cross-coupling reactions catalyzed by transition metal complexes. However, the traditional cross-coupling reaction need both organic halides and organometalic compounds, increasing the cost and the waste.Recently, Fagnou et al. reported indole synthesis from acetanilides and internal alkynes by rhodium catalysts and oxidants. This reaction can construct p-conjugated units without organohalides nor organometallic compounds.In this work, we applied the oxidative coupling to synthesis of p-conjugated polymers from 1,4-bisacetamidebenzenes and internal alkynes. The properties of these polymers are investigated by UV-vis and florescence spectroscopic measurements, CV, and DFT calculations.
