Hexadecyloxylallene was prepared by the substitution reaction of propargyl alcohol with bromohexadecane and the followed rearrangement reaction. Poly(3-hexylthiophene)-
b
-poly(hexadecyloxylallene) copolymers was then synthesized in one pot
via
sequential addition of monomers of 3-hexylthiophene and hexadecyloxylallene by using Ni(dppp)Cl
2
as a single catalyst. The products were confirmed by
1
H NMR and size-exclusion chromatography (SEC). The thermal
optical and electrical properties of the obtained block copolymer were investigated. The analysis of P3HT-
b
-PHA in the solid state using differential scanning calorimetry (DSC) and thermogravimetric analysis(TGA) revealed that the material could undergo microphase separation
as two glass transition temperatures (
T
g
) and two part of the decomposition process assignable to both P3HT and PHA phases were observed. The thin-film transistors (TFT) with bottom-gate top-contact configuration were fabricated to characterize the electrical properties of the obtained block copolymer. The TFT devices were subsequently annealed at different temperatures (room temperature
100
150
and 200 ℃) in a glovebox under nitrogen condition. The field-effect mobility shows an increasing trend when the annealing temperature increases. Thermal annealing is performed as an effective method to optimize the device performance because it can improve the crystallinity of the thin film. Meanwhile
thermal annealing can significantly lower the effect of the residual solvent on the carrier transport
resulting in efficient charge carrier transport. When the annealing temperature is 200 ℃
polymer-based OTFTs devices yield an average field-effect mobility of 7.0310
