Ultra-photostable small-molecule dyes facilitate near-infrared biophotonics

Nature Communications
Long-wavelength, near-infrared small-molecule dyes are attractive in biophotonics. Conventionally, they rely on expanded aromatic structures for redshift, which comes at the cost of application performance such as photostability, cell permeability, and ...

Dications of 3-Phenyl-indenylidene Dibenzo[ a.d ]cycloheptene: The Role of Charge in the Antiaromaticity of Cationic Systems [PDF]

, 2011
Dications of 9-(3-phenyl-1H-inden-1-ylidene)-5H-dibenzo[a,d]cycloheptene, 52+, were prepared by oxidation with SbF5 in SO2ClF, and their magnetic behavior was compared to dications of 9-(3-phenyl-1H-inden-1-ylidene)-9H-fluorene, 22+. The good correlation

The apparent and hidden variables for optimizing and functionalizing non-alternant nanographenes: A comprehensive study

Nano Trends
Atomically precise non-alternant isomers of short armchair graphene nanoribbons (AGNRs) with A = 2 armchair and Z = 3, 4 zigzag rings have been recently synthesized by introducing Stone-Wales (SW) moieties, pursuing open shell magnetic states for ...
