Core‐Fluorinated Perylene Bisimide Dyes: Air Stable n‐Channel Organic Semiconductors for Thin Film Transistors with Exceptionally High On‐to‐Off Current Ratios

Abstract

Two core-fluorinated perylene bisimide semiconductors have been synthesized and n-channel field effect transistors have been fabricated by vapor-deposition techniques. Charge carrier mobilities as high as 0.34 cm2V-1s-1 and unprecedented on-to-off current ratios around 107 have been measured for these devices in air.
