摘要	Conjugated linear polymers are promising metal-free photocatalysts for visible-light-driven photocatalytic water disinfection, but it was still bottlenecked by the insufficient photogenerated charge separation and transport (CST) process. Herein, we obtained the highly crystalline imine-linked conjugated linear poly-mer (ODA-BPAH) with a greatly enhanced CST process. The highly crystalline ODA-BPAH exhibited excel-lent broad-spectrum water disinfection efficiency up to 99.99999% in 1 h, which is among the reported highest of state-of-the-art photocatalysts. The crystallinity of ODA-BPAH was regulated by simply turn-ing the solvent and the experiment results revealed that the ODA-BPAH with high crystallinity exhibited higher internal electric field strength and photocatalytic performance than that with low crystallinity, which indicates that higher crystallinity in linear conjugated polymers contributes to superior CST ef-ficiency as well as the generation of reactive oxygen species. This work highlights the impact of poly-mer crystallinity on the internal electric field and proves that linear poly-imine could be a new type of promising metal-free photocatalyst for water treatment.
