Dithieno[ a, e]pentalene Based Conjugated Polymers: Synthesis and Characterization.

The concept of introducing π-conjugated but anti-aromatic repeating units into conjugated polymers has been explored. The thermal stability, optical and electrochemical properties of dithieno[ a, e]pentalenes (DTP) based polymers have been studied. The effect of introducing electron withdrawing repeating units into DTP based polymer on the physical properties of polymer has also been investigated. The new polymers showed broad absorption in visible and near-infrared region. [ABSTRACT FROM AUTHOR]
