High performance n-type and ambipolar small organic semiconductors for organic thin film transistors

Abstract

Remarkable progress has recently been achieved in n-type and ambipolar OFETs. In this mini review, we will highlight the representative development of high performance n-type and ambipolar organic semiconductors (OSCs) especially for those n-type small OSCs with thin film mobilities >1 cm² V⁻¹ s⁻¹, and ambipolar small OSCs with both hole and electron mobilities of over 0.1 cm² V⁻¹ s⁻¹. This overview shall provide a meaningful guideline for further development of high performance n-type and ambipolar materials and devices.
