Researchers in Japan used a series of new poly(benzothiadiazole-naphthalenediimide) derivatives and fine-tuned the material’s backbone conformation introducing vinylene bridges capable of forming hydrogen bonds with neighboring fluorine and oxygen atoms. Overall, the resultant material had an improved molecular packaging order and greater strength, which contributed to the increased electron mobility. The material achieved an electron mobility of 7.16 cm2 V-1 s-1, representing more than a 40 percent increase over previous comparable results.The researchers will also aim to improve the air stability of n-channel transistors — a crucial issue for realizing practical applications that would include CMOS-like logic circuits, all-polymer solar cells, organic photodetectors and organic thermoelectrics…read more.
