The review presents a bird-eye view on the state of research in the field of giant
nonbiological discrete metal complexes and ions of nanometer size, which are structurally …

Conspectus The ring currents of aromatic and antiaromatic molecules are remarkable
emergent phenomena. A ring current is a quantum-mechanical feature of the whole system …

Several fully π-conjugated macrocycles with puckered or cage-type structures were recently
found to exhibit aromatic character according to both experiments and computations. We …

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 …

Gain of aromaticity or relief of antiaromaticity along a reaction path are important factors to
consider in mechanism studies. Analysis of such changes along potential energy surfaces …

Singlet exciton fission photovoltaic technology requires chromophores with their lowest
excited states arranged so that 2 E (T1)< E (S1) and E (S1)< E (T2). Herein, qualitative …

The shape of the lowest singlet excited-state (S1) energy profile is of primary importance in
photochemistry and related materials science areas. Here we demonstrate a new approach …

Understanding of interactions among molecules is essential to elucidate the binding of
pharmaceuticals on receptors, the mechanism of protein folding and self-assembling of …

The exact energies of the lowest singlet and triplet excited states in organic chromophores
are crucial to their performance in optoelectronic devices. The possibility of utilizing singlet …

According to Hückel's and Baird's rules, cyclic conjugated species are aromatic either in
the ground state or in the excited state only. Thus, species with aromaticity in both states …
