Photocatalytic water splitting with organic semiconductors has proven its potential to produce hydrogen from water. In addition, chemical structure of Conjugated polymer can be easily tuned so that several important requirements for photocatalysts can be finely tuned such as absorption range, charge transport ability, exciton diffusion length, exciton lifetime and water-affinity. Here, we demonstrate that the introducing azide chemistry into F8BT colloid can be a smart strategy to improve HER. As an azide additive, BFPA is used for miniemulsion synthesis of F8BT colloid with surfactant. We further demonstrate that azide-crosslinking enhances solid-state crystalline orientation of F8BT nanoparticles by means of and FET with active layer consisting of F8BT nanoparticles show apparently higher hole mobility as a result of azide-crosslinking. This work shows that loosely bound polymer chain within nanoparticle in aqueous phase can be a bottleneck for proton reduction. |
