Research Project

Organic Electronics for Chemical Sensing

We develop different materials and device schemes for chemical sensing applications.

Drain current change of CuPc&TPFB and CoPc&TPFB devices in different gas vapors for 5 minutes; 1. methanol (>1630 ppm); 2. acetone (>3200 ppm); 3. dichloromethane (>6580 ppm); 4. ethyl acetate (>1250ppm); 5. 4.5 ppm ammonia.
