A new luminescent conjugated polymer containing triazole and triarylamine was synthesized by Suzuki coupling reaction.The polymer has well-defined structure and exhibit good thermal stability with the glass transition temperature in nitrogen at 101℃

which might be a merit for the long-life opration of light-emitting devices.The polymer is completely soluble in common solvents such as chloroform

tetrahydrofuran.Optical quality solid film is easily prepared form polymer by solution processing.The absorption spectra both the solution sample and film show three peaks

and the λ

max

are 370

290

and 245nm.The longer wavelength peak in the region of 370nm is attributed to the electron transition of along the conjuga-ted polymer main chain

the shorter wavelength peaks 290nm and 245nm are attributed to the triarylamine and triazole

respectively.The luminescent properties of the polymer in chloroform solution and in solid film were studied

the wavelengths of emission in film and solution at 458nm and 448nm.The resulting bipolar conjugated polymer emits a pure light

which is a promising candidate for polymer light emitting display.
