Polarons and cellular stimulation: Absorption and transient absorption spectra of poly(3‐hexylthiophene) nanoparticles under different pH conditions show charge‐transfer states generated by the polarization of loosely bound polymer chains. Preliminary results suggest that these states can act as precursor states for long‐living polarons; this could be beneficial for cellular stimulation.
