Abstract

An A-D-A oligomer, DTS(F ₂ BT) ₂ , was synthesized; its structural evolution was studied with DSC, POM, 2D-WAXD, and in-situ GI-XRD. The structural evolution of DTS(F ₂ BT) ₂ is stepwise and kinetically slow. Both rapid drying and the presence of PC ₇₁ BM trapped DTS(F ₂ BT) ₂ in a less ordered nematic (N) phase. PDMS-assisted crystallization enabled a pristine DTS(F ₂ BT) ₂ thin film to attain a more ordered equilibrium phase, and enhanced the OFET mobility of DTS(F ₂ BT) ₂ . In OPV devices, DIO additive drove the DTS(F ₂ BT) ₂ domains in the DTS(F ₂ BT) ₂ :PC ₇₁ BM blended film from the N phase toward the equilibrium phase, and resulted in enhanced OPV performances. These results reveal the slow ordering process of the A-D-A oligomer, and the importance of monitoring the degree of structural evolution of the active thin films in organic optoelectronics.
