Abstract
Organic semiconducting polymers dots (Pdots) have recently shown efficient photocatalytic activity for hydrogen evolution in an aqueous phase. However, colloidal Pdots face problems of aggregation and precipitation during the photocatalytic reaction due to unavoidable collisions between particles, thus resulting in a short catalytic lifetime. In this work, in situ preparation of PFBT Pdots on the surface of microbeads is reported. Results indicate that, with this facile method and support of a template, the photocatalytic properties of PFBT Pdots can be highly enhanced.

ACS Applied Energy Materials www.acsaem.org mentioned above, we report a facile method to enhance the photocatalytic stability of the PFBT semiconducting polymers by in situ preparation and immobilization of Pdots on the microbead templates
Commercially available cross-linked dextran beads, Sephadex LH-20 microbeads were used as a platform for the in situ preparation and immobilization of PFBT Pdots
Summary
Organic semiconducting polymers dots (Pdots) have recently shown efficient photocatalytic activity for hydrogen evolution in an aqueous phase. ACS Applied Energy Materials www.acsaem.org mentioned above, we report a facile method to enhance the photocatalytic stability of the PFBT ( called F8BT) semiconducting polymers by in situ preparation and immobilization of Pdots on the microbead templates (see Figure 1).
