Charge-separated states with a lifetime scale of seconds or longer not only favor studies
using various steady-state analysis techniques but are important for light-energy conversion …

Large aza‐analogues of curved polycyclic aromatic hydrocarbons with a double‐helicene
structure present unique features for molecular photonics. We present the preparation and …

Three quadrupolar D− π–A− π–D compounds, bearing alkoxy phenyls as mild electron
donors and a benzothiadiazole (A), two benzothiadiazoles (B), or a benzothiadiazole linked …

Six water-soluble bications, characterized by a symmetric A+-π-D-π-A+ structure, were
synthesized and comprehensively studied for their absorption and fluorescence properties …

Principles are presented for the design of functional near‐infrared (NIR) organic dye
molecules composed of simple donor (D), spacer (π), and acceptor (A) building blocks in a …

We report here experimental evidence of dual emission in a cationic push–pull system
(bearing a methyl pyridinium group as an electron acceptor and a diphenylamino group as …

New multimodular donor–acceptor chromophores combining phenothiazine (D′),
benzothiadiazole (A), and diphenylamine/carbazole (D) units in complex configurations (D …

The direct synthesis of diarylethynes from less‐reactive aryl chlorides and calcium carbide
was accomplished by palladium catalysis. The coupling reaction is provided with broad …

The long-standing controversy about the presence of two different emissive minima in the
lowest excited state of the cationic push–pull dye o-(p-dimethylamino-styryl) …

Time dependent density functional theory has been used to investigate the photochemical
and photophysical processes involved in the excited states relaxation of 1-and 2 …
