Anthracene‐Porphyrin Nanoribbons
Angewandte Chemie International Edition, 2023 Abstractπ‐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 infinite polymer.

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

Carbon monoxide binding to iron porphyrins [PDF]
, 1979 The carbon monoxide affinities of iron complexes of meso-tetra (α,α,α,α-o-pivalamidophenyl)porphyrin (the "picket fence" porphyrin) and of a "picket fence" porphyrin derivative with an appended axial base have been measured in solution and compared with ...

Interlocked Porphyrin Switches [PDF]
Chemistry – 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.

New two in one magnetic fluorescent nanocomposites [PDF]
, 2005 Magnetite nanoparticles have been coated by a porphyrin derivative to produce new magnetic materials with fluorescent properties. The magnetic nanoparticles were prepared using two different methods, one based on sol-gel techniques and ultrasonic ...

Inverted porphyrins and expanded porphyrins: An overview [PDF]
Journal of Chemical Sciences, 2002 Porphyrins and metallopophyrins have attracted the attention of chemists for the past 100 years or more owing to their widespread involvement in biology. More recently, synthetic porphyrins and porphyrin-like macrocycles have attracted the attention of researchers due to their diverse applications as sensitizers for photodynamic therapy, MRI ...

Improvement in the methylene blue adsorption capacity and photocatalytic activity of H₂-reduced rutile-TiO₂ caused by Ni(II)porphyrin preadsorption [PDF]
, 2011 peer reviewedH2-reduced rutile-TiO2 xerogel (Ti-700), obtained via the sol–gel process, was found to strongly adsorb the Ni(II)-5,10,15,20-tetrakis(4-carboxyphenyl)-porphyrin (NiTCPP) from a methanolic solution, despite its very low specific surface ...
