The photophysics of lumichrome, 1-methyllumichrome, and lumiflavin in water solutions
have been investigated. Fluorescence lifetimes of 2.7 and 2.2 ns were observed for …

Fluorescence solvatochromism of lumichrome (LC) was studied by steady-state and time-
resolved fluorescence spectroscopy. The excited-state properties of LC do not show any …

Some spectroscopic properties of alloxazines and the lifetimes of their singlet and triplet
states in acetonitrile are reported. In addition, the efficiencies of singlet oxygen production by …

We present a systematic study of the effect of methyl substitution on iso-and alloxazines in
acetonitrile solutions. Substitution patterns have profound effects on both spectral and …

Light-induced degradation of the riboflavin derivatives is reported, including 5-deaza-
riboflavin, iso-6, 7-riboflavin, 3-methyl-tetra-acetyl-riboflavin (3MeTARF), and 3-benzyl …

Lumichrome (L) and melamine (M) produce thermoreversible hydrogels in LM31 and LM11
compositions, but LM13 composition does not produce hydrogel (the numbers indicate the …

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

Flavin cofactors are essential for the biological function of many electron-transfer proteins.
The electron spin density distribution in the semiquinone (radical) state of the flavin ring has …

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

The electronic structure and photophysical properties of a series of N-methyl and N-acetyl
substituted alloxazines (AZs) were investigated with extensive density functional theory …
