Coherent Random Lasing Realized in Polymer Vesicles

Photonic Sensors, 2019
We have demonstrated the realization of a coherent vesicle random lasing (VRL) from the dye doped azobenzene polymer vesicles self-assembled in the tetrahydrofuran-water system, which contains a double-walled structure: a hydrophilic and hydrophobic part.

Struktureller Mechanismus eines Aktivitäts‐Photoschalters am β2‐adrenergen Rezeptor

Angewandte Chemie, EarlyView.
Zeitaufgelöste Strukturen aus Messungen an Röntgen‐Freie‐Elektronen‐Lasern in Kombination mit zellulären Assays zeigen, wie der photoschaltbare β‐Blocker Photoazolol‐1 als Wirksamkeits‐Photoschalter der Funktion des β2‐adrenergen Rezeptor wirkt. Die lichtinduzierte Neupositionierung des Liganden verschiebt die Aktivität von inversem Agonistimus hin zu ...

Supramolecular effects in dendritic systems containing photoactive groups

Anais da Academia Brasileira de Ciências, 2000
In this article are described dendritic structures containing photoactive groups at the surface or in the core. The observed supramolecular effects can be attributed to the nature of the photoactive group and their location in the dendritic architecture.

Photoswitching of Site-Selective RNA Scission by Sequential Incorporation of Azobenzene and Acridine Residues in a DNA Oligomer

Journal of Nucleic Acids, 2011
Photoresponsive systems for site-selective RNA scission have been prepared by combining Lu(III) ions with acridine/azobenzene dual-modified DNA. The modified DNA forms a heteroduplex with substrate RNA, and the target phosphodiester linkages in front of ...
