In: Angewandte Chemie International Edition, 2019, p. -

Tetraarylethenes are obtained by acid‐induced coupling of vinyl triazenes with aromatic compounds. This new C−H activation route for the synthesis of aggregation‐ induced emission luminogens is simple, fast, and versatile. It allows the direct grafting of triarylethenyl groups onto a variety of aromatic compounds, including heterocycles, supramolecular hosts, biologically relevant...

Plasmon-assisted Förster resonance energy transfer at the single-molecule level in the moderate quenching regime

Bohlen, J. ; Cuartero-González, Á. ; Pibiri, E. ; Ruhlandt, D. ; Fernández-Domínguez, A. I. ; Tinnefeld, P. ; Acuna, Guillermo P.

In: Nanoscale, 2019, vol. 11, no. 16, p. 7674–7681

Metallic nanoparticles were shown to affect Förster energy transfer between fluorophore pairs. However, to date, the net plasmonic effect on FRET is still under dispute, with experiments showing efficiency enhancement and reduction. This controversy is due to the challenges involved in the precise positioning of FRET pairs in the near field of a metallic nanostructure, as well as in the...
