Although high temperature operation (i.e., beyond 150 Celsius) is of great interest for many electronics applications, it is fundamentally challenging to achieve stable carrier mobilities for organic semiconductors at elevated temperatures. We report a general strategy to make thermally-stable high-temperature semiconducting polymer blends, composed of interpenetrating semicrystalline conjugated polymers and high glass-transition temperature insulating matrices. When properly engineered, such polymer blends display a temperature-insensitive charge transport behavior with hole mobility exceeding 2.0 cm2/Vs across a wide temperature range from room temperature up to 220 Celsius in thin-film transistors.
