Since the discovery of its facile synthesis in 2001, meso-aryl-substituted expanded
porphyrins have been developed as a new class of azaannulenes in light of their facile …

One of the most important objectives in materials, chemical, and physical sciences is the
creation of large conjugated macrocycles with well‐defined shapes, since such molecules …

Recently, Baird (anti) aromaticity has been referred to as a description of excited-state (anti)
aromaticity. With the term of Baird's rule, recent studies have intensively verified that the …

This review underscores the conformational flexibility of porphyrinoids, a unique class of
functional molecules, starting from the smallest triphyrins (1.1. 1) via [18] porphyrins (1.1 …

Modification of aromaticity is regarded as one of the most interesting and important research
topics in the field of physical organic chemistry. Particularly, porphyrins and their analogues …

Meso‐aryl expanded porphyrins present a structural versatility that allows them to achieve
different topologies with distinct aromaticities. Several studies appeared in the literature …

Eines der wichtigsten Ziele in den Materialwissenschaften, der Chemie und der Physik ist
die Herstellung von großen konjugierten Makrocyclen genau definierter Form, da solche …

Expanded porphyrins are flexible enough to switch between different π-conjugation
topologies, namely Möbius, Hückel and twisted-Hückel, each with distinct electronic …

Recently, much attention has been focused on the design and synthesis of molecules with
aromatic Möbius topology. One of the most promising applications is the manufacture of …

We have investigated the electronic structures and photophysical properties of 5, 10, 20, 25-
tetrakis (pentafluorophenyl)-substituted hexaphyrin (1.1. 1.1. 1.1)(1) and its meso-keto (2) …
