Global aromaticity at the nanoscale

Does aromaticity have a size limit? Evidence is presented for global aromaticity in porphyrin nanorings with circuits of up to 162 …

Mechanisms of IR amplification in radical cation polarons

Break down of the Born–Oppenheimer approximation is caused by mixing of electronic and vibrational transitions in the radical cations …

Time-Resolved Structural Dynamics of Extended π-Electron Porphyrin Nanoring

The design of molecular structures inspired by naturally occuring light harvesting systems has been intensely pursued over the last …

Probing the orientation of porphyrin oligomers in a liquid crystal solvent – a triplet state electron paramagnetic resonance study

Linear porphyrin oligomers have found various applications as synthetic molecular wires in the context of light harvesting, solar …

Aromaticity and Antiaromaticity in the Excited States of Porphyrin Nanorings

Aromaticity can be a useful concept for predicting the behavior of excited states. Here we show that π-conjugated porphyrin nanorings …
