Designing Thermally Stable Conjugated Polymers with Balanced Ambipolar Field-Effect Mobilities by Incorporating Cyanovinylene Linker Unit

We present a developed highly balanced and thermally stable ambipolar semiconducting polymer PBCDC consisting of diketopyrrolo[3,4-c]pyrrole and benzo[1,2-b:4,5-b′]dithiophene building blocks connected by a cyanovinylene linker unit. Stabilization of the frontier molecular orbitals and delocalization of the LUMO on the whole structural unit were realized by introducing the strong electron-withdrawing cyanovinylene linker. In addition to such electronic effects, the molecular stacking and crystallinity of the polymer film were significantly controlled by the presence of the cyanovinylene linker, which was preserved with no variation at different annealing temperatures. As a result of these electronic and structural effects of cyanovinylene, organic field-effect transistors based on the PBCDC exhibit highly balanced hole and electron mobilities of μh,max ～ 0.2 cm2 V-1 s-1 and μe,max ～ 0.2 cm2 V-1 s-1, respectively, which are virtually independent of the annealing temperature over the range of 80-250°C.

Syntheses of pyrimidine-based polymers containing electron-withdrawing substituent with high open circuit voltage and applications for polymer solar cells

Polymers using new electron-deficient units, 2-pyriminecarbonitrile and 2-fluoropyrimidine, were synthesized and utilized for the photovoltaics. Donor-acceptor (D-A) types of conjugated polymers (PBDTCN, PBDTTCN, PBDTF, and PBDTTF) containing 4,8-bis(2-octyldodecyloxy)benzo[1,2-b;3,4-b′]dithiophene (BDT) or 4,8-bis(5-(2-octyldodecyloxy)thiophen-2-yl)benzo[1,2-b:4,5-b′]dithiophene (BDTT) as electron rich unit and 2-pyriminecarbonitrile or 2-fluoropyrimidine as electron deficient unit were synthesized. We designed pyrimidine derivatives in which strong electron-withdrawing group (C-N or fluorine) was introduced to the C2 position for the generation of strong electron-deficient property. By the combination with the electron-rich unit, the pyrimidines will provide low band gap polymers with low highest occupied molecular orbital (HOMO) energy levels for higher open-circuit voltages (VOC). For the syntheses of the polymers, the electron-rich and the electron-deficient units were combined by Stille coupling reaction with Pd(0)-catalyst. Absorption spectra of the thin films of PBDTTCN and PBDTTF with BDTT unit show shift to a longer wavelength region than PBDTCN and PBDTF with BDT unit. Four synthesized polymers provided low electrochemical bandgaps of 1.56 to 1.96 eV and deep HOMO energy levels between -5.67 and -5.14 eV.

Polymer solar cells based on quinoxaline and dialkylthienyl substituted benzodithiophene with enhanced open circuit voltage

A poly[benzodithiophene-alt-di-2-thienyl-quinoxaline] series (PBDTDPQ-EH, PBDTDPQ-OD, and PBDTDPQ-HDT) was synthesized via Stille coupling. Deep highest occupied molecular orbital (HOMO) levels were achieved by the introduction of 2-decyl-4-hexyl-thiophen-yl (HDT) side chains. The introduction of the various side chains increased the molecular weight of the polymers, and the polymers dissolved well in common organic solvents at room temperature. The HOMO energy level (-5.20 to -5.49 eV) decreased because of the 2D conjugated structure. X-ray diffraction analysis showed that PBDTDPQ-OD had a slightly edge-on structure. In the case of PBDTDPQ-HDT, however, the structure was amorphous due to the thiophene side chain, and the extent of π stacking increased. After fabricating bulk-heterojunction-type polymer solar cells, the OPV characteristics were evaluated. The values of open-circuit voltage (V oc), short-circuit current (Jsc), fill factor, and power conversion efficiency (PCE) were 0.88 V, 7.9 mA cm-2, 45.4%, and 3.2%, respectively.
