The synthesis, complexation, and photophysical properties of the Eu (III)-based quinoline
cyclen conjugate complex Eu1 and its permanent, noncovalent incorporation into hydrogels …

Intermolecular excited-state proton transfer (ESPT) has been observed in several
fluorescent nucleobase and/or nucleoside analogs. In the present work, some new …

Lumichrome photophysical properties at different pH were characterized by UV–vis
spectroscopy and steady-state and time-resolved fluorescence techniques, in four forms of …

(Time-dependent) Kohn–Sham density functional theory and a combined density
functional/multi-reference configuration interaction method (DFT/MRCI) were employed to …

Flavins are a unique class of compounds that combine the features of singlet oxygen
generators and redox-dependent fluorophores. From a broad family of flavin derivatives …

The complete prototropic tautomeric mixture for xanthine (X), one of intermediates of nucleic
acids degradation, have been investigated for the first time. Fifteen NH and twenty-eight CH …

Experimental time-resolved spectral and photon counting kinetic results confirm formation of
an isoalloxazinic excited state via excited-state double proton transfer (ESDPT) catalyzed by …

Compared with isoalloxazine, the core chromophore of biologically important flavins,
alloxazine exhibits much lower fluorescence quantum yield and larger intersystem-crossing …

UV–Vis S0–Sn and T1–Tn absorption spectra of a series of isoalloxazines were calculated
using the time-dependent density-functional theory approach. In the calculations, B3LYP …

The fluorescence response of Alloxazine was found to be sensitive to solvent properties like
polarity and H-bonding capacity, which also played a significant role in controlling the …
