Porphyrin-Acetylide Grafted Gold Clusters: Synthesis, Photophysical Studies, and Explosive Sensing

, 2023
A porphyrin acetylide (P)-stabilized gold cluster (Au:P) with an average cluster diameter of 1.5 ± 0.2 nm is synthesized using a poly(vinylpyrrolidone) (PVP)-supported gold cluster (Au:PVP) precursor following the optimized biphasic ligand-exchange ...

Chiral porphyrin assemblies

Aggregate, 2023
Porphyrins are among the most important macrocycles because they perform many essential functions in living systems and serve as building blocks in many functional materials. Incorporating the chirality into porphyrins can aid biomimetic research and the

Synthesis and Spectroscopic Characterization of Some New Axially Ligated Indium(III) Macrocyclic Complexes and Their Biological Activities

Bioinorganic Chemistry and Applications, 2014
The synthesis and spectroscopic characterization of new axially ligated indium(III) porphyrin complexes were reported. Chloroindium(III) porphyrin (TPPIn-Cl) was obtained in good yield by treating the corresponding free base with indium trichloride. The

Porphyrin-Induced Protein Oxidation and Aggregation as a Mechanism of Porphyria-Associated Cell InjurySummary

Cellular and Molecular Gastroenterology and Hepatology, 2019
Genetic porphyrias comprise eight diseases caused by defects in the heme biosynthetic pathway that lead to accumulation of heme precursors. Consequences of porphyria include photosensitivity, liver damage and increased risk of hepatocellular carcinoma ...

Anthracene‐Porphyrin Nanoribbons

Angewandte Chemie International Edition, 2023
Abstract π‐Conjugated nanoribbons attract interest because of their unusual electronic structures and charge‐transport behavior. Here, we report the synthesis of a series of fully edge‐fused porphyrin‐anthracene oligomeric ribbons (dimer and trimer), together with a computational study of the corresponding ...

Bis-Porphyrin Racks with Space-Separated Co-Planar Porphyrin Rings

Molecules, 2001
A porphyrin appended norbornenyl building block 8 has been isolated and coupled, using a 1,3-dipolar ACE reaction, to yield bis-porphyrin compounds in which the porphyrin moietes are angled upward relative to the norbornane backbone.

Evaluation of the correlation between porphyrin accumulation in cancer cells and functional positions for application as a drug carrier

Scientific Reports, 2021
Porphyrin derivatives accumulate selectively in cancer cells and are can be used as carriers of drugs. Until now, the substituents that bind to porphyrins (mainly at the meso-position) have been actively investigated, but the effect of the functional ...
