Supramolecular interface decoration on a polymer conductor for an intrinsically stretchable near-infrared photodiode.

Stretchable photodiodes with near-infrared (NIR) response face the challenge of material deficiency. A supramolecular cathode with excellent optical, tensile and electrical properties was proposed. Together with a stretchable organic heterojunction, we developed an intrinsically stretchable NIR photodiode with high detectivity over 10 11 Jones and that remained functional under 100% strain.
