QYQing Yang JLJingya Li YHYanni He

Key Points

This research aims to explore how chiral supramolecular hosts can enhance circularly polarized luminescence (CPL) in achiral fluorescent dyes.
Chiral supramolecular hosts were synthesized and characterized.
Fluorescent dyes were encapsulated within these hosts to study CPL.
Circularly polarized luminescence was measured to assess effectiveness.
The encapsulated fluorescent dyes exhibited significant CPL, demonstrating marked enhancement over unencapsulated forms.
The efficiency of CPL was directly related to the structural properties of the chiral hosts.

Abstract

Chiral supramolecular hosts that induce circularly polarized luminescence (CPL) of encapsulated fluorescent dyes are considered an effective strategy for constructing CPL-active materials. Blue box, a tetracationic cyclophane featuring well-defined aromatic...
