The front cover artwork is provided by the SpectroBio research group of the Institut Lumière Matière in Lyon. The image shows the structure of Au 15 (SR) 13 , a thiolated (SR) gold nanocluster and a pictoral view of ion‐pairing of surface ligands with bulky counterions. With such ion‐pairing, a 30‐fold increase in two‐photon excited fluorescence signal at ≈600 nm can be observed. Read the full text of the article at 10.1002/cphc.201701186.
