The exciton, an excited electron–hole pair bound by Coulomb attraction, plays a key role in
photophysics of organic molecules and drives practically important phenomena such as …

The electronic excited states of molecular aggregates and their photophysical signatures
have long fascinated spectroscopists and theoreticians alike since the advent of Frenkel …

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 …

Conspectus This Account is about templates as construction tools: molecules for making
molecules. A template organizes the reactants and provides information to promote …

Large conjugated rings with persistent currents are novel promising structures in molecular‐
scale electronics. A six‐porphyrin nanoring structure that allegedly sustained an aromatic …

Electronic communication between concentric macrocycles with wave functions that extend
around their circumferences can lead to remarkable behavior, as illustrated by multiwalled …

The radical cations of a family of π-conjugated porphyrin arrays have been investigated:
linear chains of N= 1–6 porphyrins, a 6-porphyrin nanoring and a 12-porphyrin nanotube …

Molecular machines have caused one of the greatest paradigm shifts in chemistry, and by
powering artificial mechanical molecular systems and enabling autonomous motion, they …

The synthesis of ethyne-linked porphyrin nanorings has been achieved by template-directed
Sonogashira coupling. The cyclic hexamer and octamer are predicted by density functional …

Hexameric and tetrameric porphyrin nanorings, Z6· T6 and Z4· T4, were synthesized in 53%
and 14% yields, respectively, by the Sonogashira-type self-oligomerization of porphyrin …
