Facile Thioethers as Novel Class of Luminophores with Aggregation Induced Emission Properties

Vous êtes cordialement invités à la conférence du Dr. Jens VOSKUHL, Institute of Organic Chemistry, University of Duisburg-Essen, Germany, organisé par l'IPCMS.

Résumé de la conférence :

The need of novel efficient fluorophors for the recognition and labeling of biomolecules such as proteins enzymes and cells is one of the most challenging disciplines in modern biosupramolecular chemistry. Our group uses a phenomenon called aggregation induced emission. Molecules with this ability show fluorescence, contrary to normal fluorophores, when aggregated or in the solid state. Recently we found a novel class of facile thioethers with this remarkable characteristic. Our system can be easily modified and was used for the detection of proteins and bacteria. Furthermore we investigated the formation of fluorescent micelles using hydrogen bonding. Currently different compounds were investigated concerning their fluorescence properties. A range of emission in the visible region was found ranging from 430 to 590 nm. Interestingly delayed fluorescence was observed for specific compounds leading to the assumption, that and intersystem crossing to a triplet state occurs leading to a long lived fluorescence state, termed phosphorescence.
