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

Triplet–Triplet Annihilation Upconversion in a MOF with Acceptor-Filled Channels

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.

Biomimetic MOF: Extremely stable MOFs with different open metal sites and ultra-large 1D channels, PCN-222 (Fe, Mn, Co, Ni, Cu, and Zn), have been assembled with eight-connected Zr6 clusters and redox-active metalloporphyrin motifs. PCN-222(Fe) shows peroxidase-like activity in aqueous solution, exhibiting highly effective biomimetic oxidation on a number of substrates. Copyright
Chlorin-Based Nanoscale Metal-Organic Framework Systemically Rejects Colorectal Cancers via Synergistic Photodynamic Therapy and Checkpoint Blockade Immunotherapy

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
Spectroscopy of protonated tetraphenylporphyrins with amino/carbomethoxy substituents: Hyperporphyrin effects and evidence for a monoprotonated porphyrin

Spectrophotometric titrations for a full series of para-amino/carbomethoxy- substituted tetraphenylporphyrins were carried out using methanesulfonic acid in DMSO to study the hyperporphyrin effect across different substitution patterns. The series included zero, one, two (cis and trans), three, and four amino groups, with the remaining para substituents carbomethoxy groups. With increasing numbers of aminophenyl groups, the relative basicity increased and the hyperporphyrin effect increased, marked by a strong red band and a split Soret band. The cis diamino derivative showed a stronger hyperporphyrin effect compared to the trans isomer, which can be explained based on simple resonance forms. For the monoamino derivative, an initial increase in the Soret band upon acid titration along with well-defined isosbestic points provided evidence for a monoprotonated porphyrin, distinct from the diprotonated and triprotonated states. The relative stability of this unusual intermediate is proposed to be due to charge delocalization of the first cation to the single amino group and destabilization of the second protonation by the electron-withdrawing carbomethoxy substituents.
