Our group, with Josep Tent-Pérez as lead author, has published a new study in Journal of the American Chemical Society (JACS). The work investigates the ultrafast isothermal crystallization kinetics of donor–acceptor semiconducting polymers using fast scanning calorimetry (FSC), introducing a modified Malkin model to capture non-classical nucleation and crystal growth in these systems.
Abstract: "The crystallization of donor–acceptor semiconducting polymers occurs on subsecond time scales at elevated temperatures (>300 °C), preventing a rigorous kinetic description using conventional experimental approaches. Here, we use a single-step fast scanning calorimetry (FSC) methodology that enables investigating the fast isothermal crystallization kinetics of advanced donor–acceptor semiconducting polymers such as PTQ10 and D18 [...] establishing a new framework for the understanding and control of the solid-state microstructure of semicrystalline polymers."
