摘要

Ambipolar charge transport in organic semiconductors is essential for the development of integrated microelectronic organic circuits and optoelectronic devices. Widespread applications are currently hampered by the narrow choice of organic materials available. Herein we report on a "new" ambipolar organic semiconductor: the centuries-old natural dye indigo. Indigo is an intrinsically ambipolar organic semiconductor with a bandgap of 1.7 eV, high and well-balanced electron and hole mobilities of 1 × 10~(-2) cm~2 V~(-1) s~(-1) and good stability against degradation in air. Indigo-based organic field-effect transistors (OFETs) and inverters have been fabricated on natural shellac resin substrates. Inverters with high gains of 105 in the first and 110 in the third quadrant are demonstrated.
