High-Performance n-Channel Organic Transistors
High-molecular-weight (Mn) n-type semiconducting copolymers are synthesized via an improved Stille polymerization with Pd(0)/Cu(I) cocatalysts and chlorobenzene as the solvent. Due to the synergistic effects of the high Mn, rational molecular design of sp2-nitrogen substitution, and an amine-tailed self-assembled monolayer, unipolar n-channel organic transistors with remarkably high electron mobilities up to 5.35 cm2 V?1 s?1 are achieved. This is reported by Yang Wang, Tsukasa Hasegawa, Hidetoshi Matsumoto, Takehiko Mori, and Tsuyoshi Michinobu in the article https://doi.org/10.1002/adma.201707164.
