Summary

A new conjugated polymer, (poly(4-ethynylphenyl)diphenylmethyl) was prepared and characterized. The preparation involved the synthesis of a new acetylenic monomer, (4-ethynylphenyl)diphenylmethanol, which was polymerized by the well-defined catalysts (t-BuO)2Mo(=CH-t-Bu)(NAr) and [Rh(COD)Cl]2. The resulting conjugated polymer was reacted with thionyl chloride and then reduced with silver to yield a material with pendant triphenylmethyl radicals attached to the conjugated polymer chain.
