Fluorescent organotin sensing: Molecular recognition driven by halogen-bonding interactions and the phenomenon of aggregation-induced emission were combined to construct fluorescent chemosensors. Binuclear ruthenium complexes containing multiple isocyanide ligands were synthesized as nonluminescent receptors that emit red fluorescence upon interacting with organotin halides (see picture; QY=quantum yield).
