Abstract
Chirality is ubiquitous within biological systems where many of the roles and functions are still undetermined. Given this, there is a clear need to design and develop sensitive chiral optical probes that can function within a biological setting. Here we report the design and synthesis of magnetically responsive Circularly Polarized Luminescence (CPL) complexes displaying exceptional photophysical properties (quantum yield up to 31% and |g lum | up to 0.240) by introducing chiral substituents onto the macrocyclic scaffolds. Magnetic CPL responses are observed in these chiral Eu(III) complexes, promoting an exciting development to the field of magneto‐optics. The |g lum | of the 5 D 0 à 7 F 1 transition increases by 20% from 0.222 (0 T) to 0.266 (1.4 T) displaying a linear relationship between the Δg lum and the magnetic field strength. These Eu(III) complexes with magnetic CPL responses, provides potential development to be used in CPL imaging applications due to improved sensitivity and resolution.
