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.

, 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

, p. 10026 - 10029 (2017)
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.

In this work, a series of asymmetric and symmetric porphyrin derivatives (structure types: A4, A3B1,trans-A2B2,cis-A2B2, A1B3, and B4) have been synthesizedviaa one-pot method and characterized by TLC, HPLC, FT-IR,1H-NMR and UV-Vis to identify their structures and properties. The porphyrin derivatives withtrans-A2B2andcis-A2B2structures are visually distinguishedviasingle-crystal X-ray diffraction; the crystal morphology oftrans-A2B2is a needle-like structure. All porphyrin derivatives (I-VI) have excellent nonlinear optical (NLO) and optical limiting (OL) properties, and are investigated using the standardZ-scan technique. Porphyrin derivativeIIIexhibits the maximum nonlinear absorption, nonlinear refraction coefficients and optical limitation threshold, and the values are 3.7 × 10?9m W?1, ?17 × 10?17m2W?1and 0.11 J cm?2, respectively. The results demonstrate that the introduction of different substituent numbers (mono-, di- and tri-, tetra-) and substituent sites (trans-A2B2andcis-A2B2) in the porphyrins could influence the NLO and OL properties. Structure regulation of porphyrin can lead to the adjustment of NLO and OL properties, and affect its practical NLO application in the future.
