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

The ongoing race of biomedical applications has given momentum to the development of
graphene quantum dots (GQDs). GQDs are zero-dimensional fluorescent carbon …

We report the design, synthesis, and evaluation of fluorescent flipper probes for single-
molecule super-resolution imaging of membrane tension in living cells. Reversible switching …

Upon photoexcitation, a majority of quadrupolar dyes, developed for large two‐photon
absorption, undergo excited‐state symmetry breaking (ES‐SB) and behave as dipolar …

Proton-transfer reactions in water are essential to chemistry and biology. Earlier studies
reported on aqueous proton-transfer mechanisms by observing light-triggered reactions of …

A general analytical expression for the transient fluorescence spectrum is derived. The
formation of a wave packet in the excited state of a fluorophore is described, assuming that …

A thorough understanding of the microscopic mechanism of excited-state proton transfer
(ESPT) and the influence of the solvent environment on its dynamics are of great …

Excited-state proton transfer (ESPT) to solvent is often explained according to the two-step
Eigen–Weller model including a contact ion pair (CIP*) as an intermediate, but general …

Ultrafast intramolecular proton transfers of 1, 2-dihydroxyanthraquinone (alizarin-h 2) and its
deuterated product (alizarin-d 2) in dimethyl sulfoxide (DMSO) have been investigated by …

The excited-state dynamics of the push–pull azobenzene Methyl Orange (MO) were
investigated in several solvents and water/glycerol mixtures using a combination of ultrafast …
