Solution-Processed Molecular Bis(Naphthalene Diimide) Derivatives with High Electron Mobility

摘要

Organic semiconductors have attracted interest for electronic applications because of their potential for use in low-cost, large-area, flexible electronic devices. While many examples of organic semiconductors for p-channel and n-channel organic field-effect transistors (OFETs) have been reported in the recent literature, there is a paucity of high-performance, solution-processable, small-molecule materials for n-channel OFETs. In order to take advantage of the technological potential of organic semiconducting materials, solution-processable, ideally air-stable, electron-transport (ET) materials with low barriers for charge injection, high charge-carrier mobility values (>1 cm~2 V~(-1) s~(-1) ), large current on/off ratios (l_(on)/I_(off) > 10~6 ), and low threshold voltages (< ± 2.5 V) are still desirable.
