An efficient 1,3-dipolar polycycloaddition of azide and bis(benzoylethynyl)-based active internal alkynes is established. Soluble 1,4,5-trisubstituted polytriazoles with satisfactory molecular weights are prepared in excellent yields. The obtained polytriazoles are thermally stable and photosensitive, and exhibit high refractive indices.
