The synthesis and photophysical characterization of new conjugated polymers (CPs) with alternating phenylethynylene and diazobenzene (azo-PPE) units were reported, which showed broadened absorption and no measurable fluorescence. Quenching studies showed that azo-PPEs displayed high efficiency over a wide wavelength range.
