A tetrazole-containing triphenylamine-based metal–organic framework: Synthesis and photocatalytic oxidative C C coupling reaction

Metal–organic framework (MOF)-, covalent-organic framework (COF)-, and porous-organic polymers (POP)-catalyzed selective C–H bond activation and functionalization reactions

“…60 Three years later, Duan and co-workers 62 offered the construction of multivariate (MTV) Zn-based MOFs (Fig. 8) by in situ mixing the different additions of two linkers, bis(3,5-dicarboxyphenyl)methylpyridinium (H 4 L 1 ÁOH) and bis(3,5-dicarboxyphenyl)pyridine (H 4 L 2 ), denoted as ZJU-56-X (X is molar ratio of catalyst for the photooxidative C(sp 3 )-C(sp 3 ) coupling reaction of N-phenyl tetrahydroisoquinoline (PhTHIQ) and CH 3 NO 2 with a fluorescent (26 W)-light exposure time of 30 h. 63 After this, Potter et al 64 studied the catalytic activity of two Co(II)-zeolitic imidazole frameworks (ZIFs), ZIF-9 and ZIF-67, for C(sp 3 )-H activation adjacent to nitrogen towards aerobic C(sp 3 )-C(sp 3 ) bond formation reactions under visible light irradiation. With identical Co(II) ions as nodes, the organic linkers were different for the MOFs (benzimidazole for ZIF-9 and 2-methylimidazole for ZIF-67).…”

Metal–Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs) Applied to Photocatalytic Organic Transformations

“…Electron delocalization is enhanced in this type of COFs, since they are totally composed by Csp 2 -Csp 2 bonds [28].

“…In other cases, for example, Fe-O or Ti IV -O clusters present intrinsic photocatalytic activity towards the formation of reactive oxygen species, which can be used in energy transfer and electron transfer reactions [53,54]. Moreover, predesign and synthesis of intrinsically photoactive linkers (such as anthracene [36], triphenylamine [52], triazine [55], porphyrin [29], tetraphenylethylene [56], perylendiimide [57], benzoselenadiazole [58], and Ir/Ru-metal complexes [59]) are also important (Figure 5). On the other hand, in the field of COFs, the use of pristine heterogeneous catalysts represents the most employed strategy for the design of this photocatalytically active materials.…”

“…In this case, the nucleophile chosen was nitromethane, which was employed also as solvent. In 2019, He, Zhao and coworkers reported the synthesis of Cu-TPA MOF, which contains triphenylamine moieties as photosensitizers [52]. Cu-TPA presented moderated photocatalytic activity on aza-Henry reaction, being possible to recycle it up to 3 times.…”
