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 …

Charge transfer (CT) in molecular electron donor‐acceptor systems is pivotal for artificial
photosynthesis, photocatalysis, photovoltaics and fundamental photochemistry. We …

While the development of chiral molecules displaying circularly polarized luminescence
(CPL) has received considerable attention, the corresponding CPL intensity, glum, hardly …

A series of new naphthalimide and phenothiazine-based push–pull systems (NPI-PTZ1–5),
in which we structurally modulate the oxidation state of the sulfur atom in the thiazine ring, ie …

The electronically excited singlet states of nitroaromatic compounds are often presumed to
be essentially non-fluorescent. Nonetheless, a growing number of reports in the literature …

Polar and polarizable π-conjugated organic molecules containing push–pull chromophores
have been investigated extensively in the past. Identifying unique backbones and building …

A significant number of quadrupolar dyes behave as their dipolar analogues when
photoexcited in polar environments. This is due to the occurrence of excited-state symmetry …

Time-resolved electronic spectroscopy has grown into a technique that provides hundreds to
thousands of electronic spectra with femtosecond time resolution. This enables complex …

Microscopic electric fields are increasingly found to play a pivotal role in catalysis of
enzymatic and chemical reactions. Currently, the vibrational Stark effect is the main …

Electronic excitation in quadrupolar conjugated molecules rapidly localizes on a single
electron donor–acceptor (DA) branch when in polar environments. The loss of center of …
