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.
