Sketch of the experimental setup for the investigation of photoexcited states in two-dimensional organic frameworks.
Excitons are fundamental light-induced excitations, composed of bound electron-hole pairs. While they lie at the heart of photochemistry, their short-lived nature makes their experimental study a real challenge.
In the context of the recently awarded ERC starting grant (WEPOF), we are working on novel imaging techniques based on scanning probe microscopy to resolve photoexcited states in organic frameworks.
