dc.description.abstract | Through the Stille coupling polymerization, a series of soluble acceptor/donor quinoxaline/thiophene alternating conducting polymers with a hole-transporting moiety of carbazole as a side chain (PCPQT) has been designed, synthesized, and investigated. The UV-vis measurement of the chargetransferred type PCPQTs of different molecular weights with low polydispersity exhibits a red shifting of their absorption maximum from 530 to 630 nm with increasing chain length (Mn: from 1100 to 19,200). The HOMO and LUMO energy levels of PCPQT can be determined from the cyclic voltammetry measurement to be -5.36 and -3.59 eV, respectively. Solar cells made from PCPQT/PCBM bulk heterojunction show a high open-circuit voltage, Voc of ∼0.75 V, which is significantly higher than that of a solar cell made from conventional poly(3- hexyl thiophene)/PCBM as the active polymer PCPQT has lower HOMO level. Further improvements are anticipated through a rational design of the new low band-gap and the structurally two-dimensional donor-acceptor conducting polymers. © 2010 Wiley Periodicals, Inc. | - |
