A ruthenium porphyrin-based porous organic polymer (POP) was synthesized, characterized, and used to reduce CO2 to a formate salt. We demonstrate that Ru-BBT-POP can be utilized to reduce CO2 to a silyl formate and then converted to potassium formate with a respectable turnover number and frequency.

Covalent organic frameworks (COFs) have garnered immense scientific interest among porous materials because of their structural tunability and diverse properties. However, the response of such materials toward laser-induced nonlinear optical (NLO) applications is hardly understood and demands prompt attention. Three novel regioregular porphyrin (Por)-based porous COFs—Por-COF-HH and its dual metalated congeners Por-COF-ZnCu and Por-COF-ZnNi—have been prepared and present excellent NLO properties. Notably, intensity-dependent NLO switching behavior was observed for these Por-COFs, which is highly desirable for optical switching and optical limiting devices. Moreover, the efficient π-conjugation and charge-transfer transition in ZnCu-Por-COF enabled a high nonlinear absorption coefficient (β=4470 cm/GW) and figure of merit (FOM=σ1/σo, 3565) value compared to other state-of-the-art materials, including molecular porphyrins (β≈100–400 cm/GW), metal–organic frameworks (MOFs; β≈0.3–0.5 cm/GW), and graphene (β=900 cm/GW).

Porphyrin-based porous organic frameworks are an important group of materials gaining interest due to their structural diversity and distinct opto-electronic properties. However, these materials are seldom explored for nonlinear optical (NLO) applications
A chromatography-free synthesis of meso-Tetrakis(4-formylphenyl) porphyrin and meso-Tetrakis(3-formylphenyl) porphyrin: Versatile synthons in supramolecular and macromolecular chemistry

A facile synthetic strategy was developed for the synthesis of meso-Tetrakis(4-formyl-phenyl)porphyrin and meso-Tetrakis(3-formylphenyl)porphyrin from commercially available starting materials. This method gives facile access to practical amounts of these synthons in high purity and good overall yield, without employing laborious chromatographic separations. The reduction of the respective carboxylic acid-functionalized porphyrins by LiAlH4 afforded the tetra(benzylalcohol)porphyrin intermediates, subsequently utilized in a Parikh-Doering oxidation to selectively afford the desired tetraformylated products. The inherent ease of synthesis of these porphyrin building blocks provides a convenient pathway for the synthesis of various macromolecular and supramolecular architectures for applied chemical technologies.

A three step, one-pot reaction has been developed for the introduction of the formyl functional group to the meso position of porphyrins. Symmetric meso-tetrakis(4-formylphenyl)porphyrin ((CHO)4TPPH2), an important cornerstone in porphyrin chemistry, was obtained selectively in good yields via bromine-lithium exchange and subsequent Bouveault reaction. The meso-tetrakis(4-formylphenyl)porphyrin was fully characterized by HR-ESI, UV-vis, NMR, and single crystal X-ray diffraction.
