Green technology based on compostable materials is seen as an ultimate goal for solving waste problems. Currently there are large efforts for producing compostable plastic materials that can be used in daily life products, such as plastic bags, disposable dishware, etc. Organic electronics could be suitable to low-end products, where electronics may be directly integrated on plastic cups to store information, like prices, use-by-date information etc. When such daily items are produced with wastable materials, electronics included in such goods should be also based on materials that are easily degradable. Here we show first steps towards electronics based on inexpensive and non-toxic organic dielectrics and semiconductors in field-effect devices built from simple molecules on plastic substrates. The transistor characteristics (output and transfer) are stable and reproducible, showing p-type transistor characteristics with very low leakage current.
