• 

High-performance n-type organic semiconductors

• High electron mobility
  3 cm²/Vs (​solution-crystallized single-crystalline thin-film transistors under ambient air)
  >0.6 cm²/Vs (vacuum-deposited thin-film transistors)
• High reliability
  High heat stress tolerance over 150 °C and good bias stress tolerance (single-crystal OFET)
• High stability
  Long-term atmospheric stability regardless of device structure
  Decreasing rate of electron mobility is less than 10%
  
  • more than half a year by single-crystal OFET
  • more than one month by vacuum-deposited OFET
