A molecular switch in a semiconducting polymer matrix undergoes reversible interconversion between its two forms
Irradiation with either blue or green light is used to respectively "write" or "erase" information on a flexible transistor device. The molecular switch contained in a semiconducting polymer matrix undergoes reversible interconversion between its two forms, interacting (trapping) or not with the current flowing through the semiconductor.
