Front Cover: π‐Expanded Thioxanthones – Engineering the Triplet Level of Thioxanthone Sensitizers for Lanthanide‐Based Luminescent Probes with Visible Excitation (ChemPlusChem 12/2019)

Abstract

The front cover shows the clouds parting for a cell imaged using predominantly mitochondrial‐selective staining with a thioxanthone‐appended europium(III) complex. Lanthanide luminescence can therefore be used in optical bioimaging by excitation with the common blue (405 nm) laser line, thus indicating that that this type of molecular probe—following appropriate modifications—are a promising tool for the multidisciplinary imaging community. More details are given in the Full Paper by T. Just Sørensen and co‐workers on page 1778 in Issue 12, 2019 (DOI: 10.1002/cplu.201900309).
