Abstract

We have successfully synthesized two types of conjugated polymers, i.e., ladder-type or AB-type poly(benzopentalene) derivative macromoleculars, by Pd-catalyzed self-polycondensation. Incorporating long alkyl chains at the polymer peripheral positions, both polymers have very good solubility and high molecular weight. Thus, the detailed optical and electrochemical properties of the polymers were investigated. At the same time, it was very special that one type of conjugated polymer possessed reactive side groups which can be “clicked” by tetrathiafulvalene (TTF). The energy levels can be obviously changed by the “click” reaction. These results show that ladder-type poly(benzopentalene) derivatives containing reacted side groups are promising candidates for achieving optoelectronic applications.
