Porphyrin Wheels [PDF]

open access: yesJournal of the American Chemical Society, 1996
A simple method to prepare porphyrin 'wheels' on a micrometer scale is described. It is possible to arrange several types of porphyrin derivatives, including Protoporphyrin IX and Chlorophyll-a, in the form of rings using this method. A mechanism for the formation of these types of assemblies is proposed that is based on the generation of '2D-gas ...

Anthracene‐Porphyrin Nanoribbons

open access: yesAngewandte 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 ...

Interlocked Porphyrin Switches [PDF]

open access: yesChemistry – A European Journal, 2013
AbstractWe describe the synthesis of a series of interlocked structures from porphyrin–glycoluril cage compounds and bis(olefin)‐terminated viologens by an olefin‐metathesis protocol. The length of the chain connecting the olefin substituents with the viologen has a marked effect on the products of the ring‐closure reaction.

Urinary porphyrin excretion in hepatitis C infection [PDF]

open access: yes, 1999
A high prevalence of hepatitis C virus infection in porphyria cutanea tarda in some populations suggests a close link between viral hepatitis and alteration of porphyrin metabolism.

The Synthesis of a π-Extended Tetrathiafulvalene Porphyrin for MOF Formation and Use in Solar Cells [PDF]

open access: yes, 2018
With the purpose of creating a conjugated system for potential experiments in solar cell applications, the first π-extended TTF (ExTTF) porphyrin with a functionalizable handle (carboxylic ester) was synthesized. The overall yield was 0.249%.

Immobilized photosensitizers for antimicrobial applications [PDF]

open access: yes, 2015
Photodynamic antimicrobial chemotherapy (PACT) is a very promising alternative to conventional antibiotics for the efficient inactivation of pathogenic microorganisms; this is due to the fact that it is virtually impossible for resistant strains to ...

Peripherally-metallated porphyrins: meso-n1-porphyrinyl-platinum(II) complexes of 5,15-diaryl- and 5,10,15-triarylporphyrins [PDF]

open access: yes, 2002
Attempted metathesis reactions of peripherally-metallated meso-η1-porphyrinylplatinum(II) complexes such as trans-[PtBr(NiDPP)(PPh3)2] (H2DPP = 5,15-diphenylporphyrin) with organolithium reagents fail due to competitive addition at the porphyrin ring ...

Regioselective and stoichiometrically controlled conjugation of photodynamic sensitizers to a HER2 targeting antibody fragment [PDF]

open access: yes, 2014
The rapidly increasing interest in the synthesis of antibody–drug conjugates as powerful targeted anticancer agents demonstrates the growing appreciation of the power of antibodies and antibody fragments as highly selective targeting moieties.
