Abstract

Contrasting mechanochromic luminescence (MCL) has been observed for enantiopure and racemic crystals of pyrenylprolinamides with different substituents. Enantiopure crystals exhibited circularly polarized luminescence (CPL), and mechanochromic CPL was achieved due to the formation of hydrogen-bonded excimers in the amorphous state. For the first time, the amorphous-state CPL was elucidated based on the excimer chirality rule.
