Visible Light-Driven D–A Conjugated Linear Polymer and Its Coating for Dual Highly Efficient Photocatalytic Degradation and Disinfection

in 7 h. These inactivation efficiency results are among those of the best reported D-A conjugated linear polymers. Importantly, PBDT-F-COOH and the PBDT-F-COOH-PU coating both presented satisfactory stability with high photocatalytic activity after recycling runs. This work provides a feasible approach for fabricating nontoxic and highly active organic photocatalysts with wide visible spectra and a large dipole moment via a D-A linear structure design protocol.
