Polymer Bulletin Aims and scope Submit manuscript

Summary

Novel organoboron polymers containing pyrazabole and electron withdrawing moiety in the main chain were prepared by Heck-Sonogashira coupling. The coupling reaction between various diyne monomers and pyrazabole derivatives gave the corresponding polymers in good yields. The optical properties of the obtained polymers were investigated by UV-vis absorption and fluorescence spectroscopy. The relation between the electron density on the boron atoms and the optical properties of the corresponding polymers was also studied.
