The relationship between photophysical properties and aromaticity/antiaromaticity of various expanded porphyrins — a Hans Fischer Career Award paper

Understanding aromaticity is crucial for predicting the molecular properties and reactivity of cyclic [Formula: see text]-conjugated systems. In this review, representative reports on the evaluation of aromaticity via spectroscopic methods in various expanded porphyrin systems are presented. The relationship between the photophysical properties and distinct aromatic characteristics in Hückel aromatic compounds was revealed through notable spectroscopic features exhibited by aromatic expanded porphyrins. Furthermore, modulating the molecular conformation and chemical environment enabled us to distinguish unique Möbius aromatic molecules successfully. These findings provide insight into the elemental molecular properties and aromaticity in expanded porphyrin systems and their potential real-world applications.

Spin-filter transport and magnetic properties in a binuclear Cu(ii) expanded porphyrin based molecular junction

The Spin-filter transport properties of a magnetically coupled, binuclear Cu(ii) expanded porphyrin based molecular junction, were studied at different bias and gate voltage values, through the DFT-NEGF methodology.

Correction: UO22+-mediated ring contraction of pyrihexaphyrin: synthesis of a contracted expanded porphyrin-uranyl complex

Correction for ‘UO22+-mediated ring contraction of pyrihexaphyrin: synthesis of a contracted expanded porphyrin-uranyl complex’ by James T. Brewster et al., Chem. Sci., 2019, 10, 5596–5602.

UO22+-mediated ring contraction of pyrihexaphyrin: synthesis of a contracted expanded porphyrin-uranyl complex

A new mixed hexaphyrin, pyrihexaphyrin (0.1.0.0.1.0) (1), was prepared via an acid catalyzed cyclization between 5,5′-(pyridine-2,6-diyl)bis(pyrrole-2-carbaldehyde) (2) and terpyrrole (3).
