Swivel-cruciform oligothiophene dimers

Synthesis and electronic properties of three swivel-cruciform oligothiophene dimers - bis(terthiophene) (BT3), bis(pentathiophene) (BT5) and bis(heptathiophene) (BT7) - with increased solubility in organic solvents are reported. We obtained a field-effect mobility of 3.7 × 10-5 cm2 V-1 s-1 and a current on/off ratio of >103 for a solution-processed OFET device with dimer BT5 as p-type semiconductor.

Dopant-free 3,3′-bithiophene derivatives as hole transport materials for perovskite solar cells

Three 3,3′-bithiophene derivatives (DHPT-SC, DOPT-SC and DEPT-SC) have been efficiently synthesized by a Stille reaction. X-ray diffraction analysis revealed unique swivel-cruciform configurations and weak intermolecular π-π stacking in these materials. Perovskite solar cells using these pristine hole transport materials without dopants have achieved power conversion efficiencies of 8.35%, 8.69%, and 9.73% with good air stability. This present finding develops dopant-free hole transport materials for perovskite solar cells.
