Chiral Dipicolinamide‐Based Push–Pull π‐Conjugated Systems as Nonreciprocal Circularly Polarized Luminescence Emitters
ABSTRACT We report the synthesis of a new family of chiral dipicolinamide systems presenting an extended π‐conjugated backbone connecting an electron‐donating group (─NMe 2 ) to a pyridine unit. The chirality is introduced on the amide chains located at positions 2 and 6 of the pyridine, by employing commercially available enantiopure amines. Besides the good quantum yields shown in solution (up to 15%), two of the synthesized molecules are endowed with nonreciprocal chiroptical properties when they form thin films on a glass substrate, showing a strong circularly polarized luminescence with |g lum | values as high as 0.06.
