Presolski, Stanislav I.,Van Der Weegen, Rob,Wiesfeld, Jan J.,Meijer
, p. 1864 - 1867 (2014)
A3B-type meso-(4-carboxyphenyl) porphyrins were prepared either by stepwise coupling of aniline substituents to meso-tetrakis(4-carboxyphenyl) porphyrin (TCPP) or by utilizing its partially protected trimethyl ester derivative. We demonstrate t

Photon upconversion has enjoyed increased interest in the last years due to its high potential for solar-energy harvesting and bioimaging. A challenge for triplet–triplet annihilation upconversion (TTA-UC) processes is to realize these features in solid materials without undesired phase segregation and detrimental dye aggregation. To achieve this, we combine a palladium porphyrin sensitizer and a 9,10-diphenylanthracene annihilator within a crystalline mesoporous metal–organic framework using an inverted design. In this modular TTA system, the framework walls constitute the fixed sensitizer, while caprylic acid coats the channels providing a solventlike environment for the mobile annihilator in the channels. The resulting solid material shows green-to-blue delayed upconverted emission with a luminescence lifetime of 373±5 μs, a threshold value of 329 mW cm?2 and a triplet–triplet energy transfer efficiency of 82 %. The versatile design allows straightforward changing of the acceptor amount and type.
Chlorin-Based Nanoscale Metal-Organic Framework Systemically Rejects Colorectal Cancers via Synergistic Photodynamic Therapy and Checkpoint Blockade Immunotherapy

, p. 12502 - 12510 (2016)
Photodynamic therapy (PDT) can destroy local tumors and minimize normal tissue damage, but is ineffective at eliminating metastases. Checkpoint blockade immunotherapy has enjoyed recent success in the clinic, but only elicits limited rates of systemic ant

A porphyrinic metal-organic framework (MOF), PCN-222(Fe), was found to exhibit sound activity and selectivity to cyclohexanone and cyclohexanol (known as KA oil) toward cyclohexane oxidation. Remarkably, hydrophobicity engineering of the MOF pore walls le
NMR Spectra of the Porphyrins Part 39. Paramagnetic Shifts in Cobalt(II) Porphyrins
Abraham, Raymond J.,Marsden, Ian,Xiujing, Lucy
, p. 1051 - 1057 (1990)
A model of the paramagnetism in cobalt(II) porphyrin complexes has been developed which successfully calculates paramagnetic shifts for protons not affected by the contact term.The model utilizes a single large dipole positioned on the cobalt(II) atom, an
Dye-sensitized solar cells using supramolecular porphyrin arrays inspired by π-stacking structures of photosynthetic light-harvesting complexes
Fujimoto, Junko,Manseki, Kazuhiro,Miyaji, Hidekazu
, p. 207 - 209 (2014)
A slipped cofacial π-stacks of bis(4-carboxyphenyl)bis(1- methylimidazol-2-yl)porphyrinatomagnesium complex can be self-assembled onto TiO2 surface as a light-harvesting core. The porphyrin array allows a more favorable light-to-electricity conversion compared to the monomer analogue in dye-sensitized solar cells.

Among MOFs, chromium-based metal–organic frameworks (Cr-MOFs) represent attractive scaffolds for variety of potential applications due to their high porosity and stability. Nevertheless, Cr-MOFs are not very common due to complicate synthesis. Cr-MOFs of large linkers are one clear example of synthetic limitations, since their preparation takes place by post-synthetic routes, commonly starting from Fe-MOFs as precursors. Hence, in this work, the direct synthesis of a phorphyrinic chromium-based MOF, Cr-PCN-600 (PCN stands for Porous Coordination Network) under solvothermal conditions is reported. The resulting Cr-MOF exhibits high surface area, permanent porosity, and broad light absorption wavelength range. Interestingly, this Cr-MOF is a highly effective heterogeneous photocatalyst for the selective aerobic oxidation of benzyl alcohol to benzaldehyde under visible light irradiation without any additive. Importantly, the Cr-MOF showed good recyclability maintaining its activity for three runs. The present results lay the foundation for both synthesis and applications of Cr-MOFs as robust photocatalysts in advanced organic transformations. Notably, quenching studies confirmed the generation of superoxide radical anion (O2[rad]?) and singlet oxygen (1O2) (mostly) as reactive species under the reaction conditions.
