Charge and proton transfer reactions in the excited states of organic dyes can be coupled in
many different ways. Despite the complementarity of charges, they can occur on different …

Abstract The “Excited-State Intramolecular Proton Transfer”(ESIPT) reactions in a number of
organic fluorophores are among the fastest basic chemical reactions known so far and their …

Fluorescent probes for sensing fundamental properties of biomolecular environment, such
as polarity and hydration, help to study assembly of lipids into biomembranes, sensing …

The solid-state fluorescence intensity of coumarin dyes depends on the substituents present
at the 4-and 7-positions. 7-(Diethylamino) coumarins showed higher solid-state …

Abstract The 2-Phenyl, 3-Hydroxybenzo [g] quinolone (2P3HBQ) fluorophore and its
derivative, 2-(4′-hydroxyphenyl)-3-hydroxybenzo [g] quinolone (2HP3HBQ), exhibit well …

We developed a new generic fluorescence sensing technology based on the change of
relative intensities between two well-separated emission bands of the novel functional 3 …

Wavelength ratiometry (often abbreviated as λ-ratiometry) is one of the most popular
methods to study intermolecular interactions that allows obtaining both thermodynamic and …

3-Hydroxyquinoline-4 (1 H)-ones (3HQs) are privileged structural motifs. The current
methods for their synthesis necessitate strongly acidic or basic conditions, which hamper the …

Synthesis of aza‐rocaglates, nitrogen‐containing analogues of the rocaglate natural
products, is reported. The route features ESIPT‐mediated (3+ 2) photocycloaddition of 1 …

3-Hydroxyquinolones undergo excited-state intramolecular proton transfer (ESIPT), resulting
in a dual emission highly sensitive to H-bonding perturbations. Here, we report on the strong …
