Abstract

Pump-probe measurements of phase-separated conjugated-polymer films, combining 150-fs temporal and 300-nm spatial resolution, allow one to highlight “dynamical” interfaces, i.e. borders of phase-separated islands that behave differently in terms of transient absorption and relaxation dynamics.
