Dynamics of conformational relaxation in photoexcited oligofluorenes and polyfluorene (2006)
Journal Article
Hintschich, S., Dias, F., & Monkman, A. (2006). Dynamics of conformational relaxation in photoexcited oligofluorenes and polyfluorene. Physical review B, 74(4), https://doi.org/10.1103/physrevb.74.045210

In order to disentangle the relaxation effects of exciton migration and conformational rearrangement, a comparative study of a polyfluorene derivative and short oligofluorenes is carried out. We probe their long-time time-dependent relaxation in dilu... Read More about Dynamics of conformational relaxation in photoexcited oligofluorenes and polyfluorene.

Intramolecular charge transfer assisted by conformational changes in the excited state of fluorene-dibenzothiophene-S,S-dioxide co-oligomers. Journal of Physical Chemistry B (Soft Condensed Matter and Biophysical Chemistry), 110(39), 19329-19339. https://doi.org/10.1021/jp0643653

The strong solvatochromism observed for two fluorene-dibenzothiophene-S,S-dioxide oligomers in polar solvents has been investigated using steady-state and time-resolved fluorescence techniques. A low-energy absorption band, attributed to a charge-tra...

We observe folding of horse heart cytochrome c in various environments including nano-compartments (micelles and reverse micelles). Using picosecond-resolved Förster resonance energy transfer (FRET) dynamics of an extrinsic covalently attached probe...

The luminescence decay kinetics of polyfluorene copolymers containing fluorenone units randomly distributed along the polymer chain have been Studied by steady-state and time-resolved fluorescence techniques in toluene solution. The typical green emi...

Bridged diiridium complexes for electrophosphorescent OLEDs : synthesis, X-ray crystal structures, photophysics, and devices. Journal of materials chemistry, 16(11), 1046-1052. https://doi.org/10.1039/b515258e

Results are presented which challenge the accepted view that dinuclear transition metal–ligand complexes are unsuitable for organic light-emitting device (OLED) applications due to their low luminescence quantum efficiencies. We establish for the fir... Read More about Bridged diiridium complexes for electrophosphorescent OLEDs : synthesis, X-ray crystal structures, photophysics, and devices..
