Front Cover: Mechanochromic Luminescence and Solid‐State Circularly Polarized Luminescence of a Chiral Diamine‐Linked Bispyrene (ChemPhotoChem 10/2021)

Abstract

The Front Cover illustrates the change in circularly polarized luminescence (CPL) of a chiral diamine‐linked bispyrene caused by two types of mechanical stimuli, namely ultrasonication and grinding, analogous to the volcanic eruption and the collision of two volcanic rocks depicted in the image.
