Abstract

Abstract: The front cover artwork is provided by the SpectroBio research group of the Institut Lumière Matière in Lyon. The image shows the structure of Au15 (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 . Abstract : "We show that by an appropriate choice of bulky counterions and of solvent, a 30‐fold increase in two‐photon excited fluorescence (TPEF) signal at ≈600 nm for gold nanoclusters can be obtained…" This and more about the story behind the front cover can be found in the Communication at10.1002/cphc.201701186 .
