title: A photoswitchable poly(3-hexylthiophene).
abstract: A well-defined main-chain conjugated photoswitchable poly(3-hexylthiophene) with homogeneous hydrogen end groups was synthesized. Opening and closing the photoswitch enables reversible modulation of P3HT emission, which is quenched by 70% when the switch is closed. The optical properties during switching cycles were quantified by irradiation/spectroscopy sequences.
