Flexible covalent porphyrin framework film: An emerged platform for photocatalytic C H bond activation

In Situ Prepared NRCPFs as Highly Active Photo Platforms for in Situ Bond Formation Between Aryldiazonium Salts and Heteroarenes

“…The zeta potential value was also observed by dynamic light scattering (DLS). The zeta potential value of NRCPFs photocatalyst (À21.5 mV) is more negative (see in Figure S7) than DCB monomer (À5.92 mV), which clearly indicates the formation of highly efficient newly designed NRCPFs photocatalyst as per reported literature methods (42,43).…”

“…Subsequently, the outstanding yield was obtained at the optimized reaction condition where 10 eq. heteroarene derivatives mixed in high polar solvent DMSO (dimethyl sulfoxide); here, we achieved a yield of 99.3% with the conversion of 99.5% of the substrate (Table 1, entry 2) as per reported literature (43). Control experiments/optimization reaction was pursued in the presence/absence of newly designed photocatalyst and light as shown in Table 1.…”

Porphyrin-Containing MOFs and COFs as Heterogeneous Photosensitizers for Singlet Oxygen-Based Antimicrobial Nanodevices

“…Nanosized composites containing porphyrin-based MOFs for antibacterial applications have been thoroughly explored, and evidence for synergic actions has been unambiguously provided. Concurrently, despite the fact many composites of porphyrin-based COFs have been described thorough the literature, particularly during the past three years, ,− composite materials using the photosensitizer porphyrins dedicated for generating ROS has been modestly employed. To the best of our knowledge, there is only one study reporting a composite material with graphitic carbon nitride (g-C 3 N 4 @COF) aiming at pollutant destruction in water .…”

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

“…The deposited material showed interesting photocatalytic activity towards the cross-coupling of trifluoroborate diazonium salts and different 5-membered heterocycles. 189 The proposed mechanism (Fig. 16) starts with the formation of the aryl radical after nitrogen gas extrusion, triggered by the excited state of the catalyst.…”
