Abstract:In this work, we prepared poly(3-butylthiophene) (P3BT) samples with different polymorphs by spin-coating a P3BT solution to form P3BT films and then carbon disulfide (CS 2 ) vapor annealing and thermal annealing these P3BT films. Combining UV−visible (UV−vis) spectroscopy, grazing-incidence wideangle X-ray diffraction (GIXRD), and Fourier transform infrared (FTIR) spectroscopy, we found that both form I and form I′ of P3BT can be doped with 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ), wherei… Show more
