B←N bonds alter the photo-generated electron/hole separation ability of conjugated polymers to promote photocatalytic performance

Abstract

Conjugated polymers have gained much attention due to their ability to efficiently convert solar energy into hydrogen. However, the low photo-generated electron/hole separation and transport capabilities limit the development of...

Hollow sp2-conjugated covalent organic framework encapsulating thiophene-based photosensitizer for enhanced visible-light-driven hydrogen evolution

“…The utilization of conjugated polymer semiconductors in solar-driven photocatalytic water splitting shows great potential as an environmentally friendly method to generate hydrogen (H 2 ). 1,2 The bandgaps of polymer photocatalysts can be precisely tailored through careful design of their electronic structures, leading to enhanced absorption efficiency within the visible region. 3,4 Recently, the finely tuned band structures of Z-scheme heterostructures discovered at the molecular level have attracted great attention in water splitting.…”
