Journal ArticleDOI
Reversible single-molecule photoswitching in the GFP-like fluorescent protein Dronpa
Satoshi Habuchi,Ryoko Ando,Peter Dedecker,W. Verheijen,Hideaki Mizuno,Atsushi Miyawaki,Johan Hofkens +6 more
TL;DR: The perfect reversibility of the Dronpa photoswitching is reported and a detailed model, which quantitatively describes interconversion among the various states is proposed, which holds great promise for following fast diffusion or transport of signaling molecules in live cells.
Journal ArticleDOI
Fluorescence Detection from Single Dendrimers with Multiple Chromophores
Thomas Gensch,Johan Hofkens,Andreas Heirmann,Kenji Tsuda,W. Verheijen,Tom Vosch,T. Christ,Thomas Basché,Klaus Müllen,Frans C. De Schryver +9 more
TL;DR: The differences in the fluorescence behavior of a polyphenylene dendrimer with eight peryleneimides chromophores and a single hexaphenylperyleneimide chromophore have been investigated at a single-molecule level through the combination of ultrasensitive fluorescence detection and microscopy.
Journal ArticleDOI
Effect of Core Structure on Photophysical and Hydrodynamic Properties of Porphyrin Dendrimers
Mauricio S. Matos,Johan Hofkens,W. Verheijen,F. C. De Schryver,Stefan Hecht,K. W. Pollak,Jean M. J. Fréchet,B. Forier,Wim Dehaen +8 more
TL;DR: The photophysical and hydrodynamic properties of dendrimers with zinc porphyrin and tetraphenylporphyrin (TPP) cores are studied in tetrahydrofuran (THF) and dimethylformamide (DMF) as mentioned in this paper.
Journal ArticleDOI
Solvent Dependence of the Hydrodynamical Volume of Dendrimers with a Rubicene Core
TL;DR: In this article, a dendrimer with a fluorescent core consisting of a rubicene moiety is synthesized and the hydrodynamical volume is determined in toluene, a good solvent, acetone, a medium quality solvent, and acetonitrile, a poor solvent.
Journal ArticleDOI
Direct measurement of the end-to-end distance of individual polyfluorene polymer chains
Benoit Muls,Hiroshi Uji-i,Sergey M Melnikov,Alain Moussa,W. Verheijen,Jean-Philippe Soumillion,Jacob Josemon,Klaus Müllen,Johan Hofkens,Johan Hofkens +9 more
TL;DR: Wide-field imaging of individual multichromophoric molecules and successive photobleaching were used to determine, accurately, the relative position of the chromophores in such systems and it was found that the polymer has a nonlinear conformation.
