) (PPV) derivative was synthesized via the Gilch route, which emits in the blue-greenish region. The required monomer synthesis is a multistep process starting from catechol and does not involve any critical step. The polymer synthesis itself proceeds via standard Gilch conditions and results in constitutionally homogeneous and extraordinary high-molecular-weight PPVs. The characterization of these
