A polymer P1 was successfully synthesized through the Wittig-Horner reaction by employing fluorene and 9,10-distyrylanthracene moieties as building blocks for backbone and tetraphenylethenes as pendant groups.Photophysical and thermal properties of the resulting polymeric emitter were fully characterized by ultraviolet-visible(UV-vis)absorption and photoluminescence(PL)spectra,thermogravimetric analysis(TGA)and differential scanning calorimetry(DSC).While P1 emits an orange-light centered at 567 nm in dilute tetrahydrofuran(THF)solution,the solid powder of the polymer exhibits strong yellow emission peaked at 541 nm.
