Abstract:
We report a self-referenced ratiometric nanothermometer based on short conjugated polyelectrolytes. An amphiphilic macromolecule destabilizes the polymer π-π stacking and makes it possible to shift the equilibrium between the less emissive aggregated state (520 nm) and the brighter individual chain (450 nm) within 20.0 °C and 70.0 °C.
