Intramolecular charge transfer assisted by conformational changes in the excited state of fluorene-dibenzothiophene-S, S-dioxide co-oligomers

Article Abstract:

Steady-state and time-resolved fluorescence techniques were used to investigate the strong solvatochromism observed for two fluorene-dibenzothiophene-S, S-dioxide oligomers in polar solvents. The solvatochromism and thermochromism of both compounds demonstrate that the molecules, in their excited states, undergo an intramolecular charge-transfer reaction stabilized by the solvent polarity and accompanied/followed by molecular structural changes.

Electrochemistry, spectroscopy, and electrogenerated chemiluminescence of some star-shaped truxene-oligofuorene compounds

Article Abstract:

The electrochemical analysis, spectroscopy, and electrogenerated chemiluminescence (ECL) of four monodisperse star-shaped truxene core-oligofluorene compounds are described. The oligomers demonstrate electrochemistry in a MeCN/Bz solution with fair stability of both anion and cation radicals.

Direct conjugation of semiconductor nanocrystals to a globular protein to study protein-folding intermediates

Article Abstract:

The synthesis of luminescent semiconductor nanocrystals covalently attached to a transporter protein human serum albumin (HSA) as fluorescent biological labels is reported. The studies could be used as an efficient probe to monitor the intermediates of protein folding.
