摘要：

Organic semiconducting polymers have attracted intense interest for a variety of applications like organic light-emitting diodes (OLED), organic photovoltaic (OPV), and organic thin-film transistors (OTFT). Ageneral synthesis of PBTDTT-15 is schematically depicted in Scheme 1 with the detailed synthetic procedures described in the Supporting Information. PBTDTT-15 was chosen for its solution processability by virtue of the presence of two long pentadecyl side chains on the DTT repeating units. The FET properties of a solution-processed PBTDTT-15 semiconductor thin film were evaluated using a bottom-gate, top-contact TFT configuration built on an n-doped silicon wafer with evaporated gold source/drain electrodes and octyltrichlorosilane (OTS)-modified 200 nm SiO2 gate dielectric on silicon wafer surface.
