“…49 Meanwhile, Cu(II) and Ni(II) have different electronic congurations and geometries, which may also inuence the photocatalytic activity. 50,51 In addition, based on the good catalytic performance of complexes 1-2, the catalytic performance of 1-2 for methylene blue (MB) and methyl orange (MO) was measured. The experimental results are shown in Fig.…”

“…For the porous heterogeneous photocatalysts, their excellent photocatalytic performance is usually determined by the large specific surface area. , This is also true for the open-AEDTE-H 2 TIPP-POP with the biggest specific surface area, which exhibits the most prominent catalytic behavior among the series of polymers. The TON (74) of open-AEDTE-H 2 TIPP-POP as a heterogeneous photocatalyst is much better than that for the excellent photocatalysts, including Eosin Y (TON, 42) and potassium 2-formylphenolate (TON, 6.5). , For the two metalated polymers with similar surface areas, the photocatalytic performance of open-AEDTE-FeTIPP-POP is slightly better than that of open-AEDTE-ZnTIPP-POP because of the paramagnetic ions, which is helpful for the electron-transfer involving photocatalytic activity. , …”

Open-AEDTE-H 2 TIPP-POP was readily recovered from the reaction mixture via centrifugation.…”

Sonogashira–Hagihara coupling reaction of photoswitchable dithienylethene (AEDTE) with metal-free 5,10,15,20-tetrakis(4-iodophenyl)porphyrin and its metal derivatives (MTIPP, M = H2, Zn(II), Fe(II)) results in three porous organic polymers (POPs) including AEDTE-H2TIPP-POP, AEDTE-ZnTIPP-POP, and AEDTE-FeTIPP-POP. The morphology, components, and structures of newly obtained POPs have been examined by a range of spectroscopic and microscopic techniques including infrared spectroscopy (IR), solid-state UV–vis diffuse reflectance spectroscopy, thermogravimetric analysis (TGA), powder X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The porous structures have been estimated by nitrogen and carbon dioxide sorption isotherms at 77 and 196 K, respectively. The open-AEDTE-H2TIPP-POP with AEDTE in an open form was revealed to be an effective and stable heterogeneous photocatalyst for visible light-driven oxidation of N-methylpyridinium salts possibly because of its relatively large specific surface area. In particular, a proof-of-concept of photoswitchable POP photocatalysts has been established using different light irradiation upon open-AEDTE-H2TIPP-POP to control its heterogeneous photocatalytic behaviors because of the adjustment over the electron transfer process and porous structures through photoisomerization of AEDTE. The present result highlights the bright perspective of photoswitching POPs in the field of materials chemistry and catalysis community.
