Donor-acceptor conjugated heptazine polymers: Boosting the Cr(VI) photoreductions via heteroatom engineering

NIR-II light-response porphyrin-heptazine-based conjugated organic polymers for highly efficient photooxidation

“…41 Noticeably, the intensities of CuTPP-Cy and NiTPP-Cy are higher, compared with those of H 2 TPP-Cy, which may be caused by increased crystallinity with the introduction of metal. 42 To further illustrate the connection between s -heptazine and porphyrins units in MTPP-Cys, FT-IR measurements were performed. As presented in Fig.…”
