Abstract
AbstractEfficient circularly polarized luminescence (CPL) from purely organic molecules holds great promise for applications in displays, sensing, and bioimaging. However, achieving high dissymmetry values (glum) from organic chromophores remains a significant challenge. Herein, we present a bioinspired approach using adenosine triphosphate (ATP)‐triggered supramolecular polymerization of a naphthalene diimide‐derived monomer (ANSG) to induce CPL with a remarkable glum value of 1.1×10−2. The ANSG molecules undergo a templated, chiral self‐assembly through a cooperative growth mechanism in the presence of ATP, resulting in scrolled nanotubes with aggregation‐induced enhanced emission (AIEE) and induced CPL. Furthermore, we demonstrate the concept of chiroptical amplification of induced CPL by efficiently amplifying asymmetry using a mixture of chiral ATP and achiral pyrophosphate. This innovative approach opens numerous opportunities in the emerging field of circularly polarized luminescence.
