Design, characterization and properties of nitrogen-containing novel organic N-type materials
Published 2013“…In past decades,organic semiconductors have caused a lot of interests because of their potential applications in field-effect transistors(FET),organic-light-emitting devices(OLED)and photovoltaic cells.Among them,developing high-efficient n-type organic materials for organic field-effect transistors(OFETs)is very urgent.Currently, p-type organic semiconductors are well-developed and their mobility can go as high as4.8 cm2V-1S-1.Since p-type and n-type materials are equally important for the fabrication of p-n junctions and complementary logic circuits,the demand to find the promising n-type counterparts is necessary. …”
