Abstract

Structural and electronic criteria for ambient stability in n-type organic materials for organic field-effect transistors (OFETs) are investigated by systematically varying LUMO energetics and molecular substituents of arylene diimide-based materials. Six OFETs on n+-Si/SiO2 substrates exhibit OFET response parameters as follows: N, N'-bis (n-octyl) perylene-3, 4: 9, 10-bis (dicarboximide)(PDI-8): μ= 0.32 cm2 V-1 s-1, V th= 55 V, I on/I off= 105; N, N'-bis (n- ...
