Lanthanide Centered and Circular Polarized Luminescence (CPL) From Tb(III) Complexes Made From Structurally Simple Methoxy‐Phenyl and Phenol‐Derived Pyridyldiamide (pda) Ligands

Chemistry – A European Journal, EarlyView.
The development of chiral pda derived methoxy ligands L1a [1(R,R)] and L1b [1(S,S)], along with their phenol derivatives L2a [2(R,R)] and L2b [2(S,S)], and their respective Tb(III) complexes is described. These Tb‐complexes exhibited Tb(III)‐centered emission upon and their chiroptical properties were probed by using both CD and CPL spectroscopy ...

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

Chemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Synthesis of Chiral‐at‐Sulfur(VI) Sulfonimidamide Brønsted Acids

Chemistry – A European Journal, EarlyView.
A simple, modular route to chiral‐at‐sulfur(VI) Brønsted acids is described, delivering S‐chiral sulfonimidamides, C2‐symmetric acids, and BINOL‐based hybrid systems through stereospecific reactions of sulfonimidoyl fluorides and chlorides. ABSTRACT Herein, we report an efficient and simple strategy to access diverse chiral‐at‐sulfur(VI) Brønsted acids.

Chiral Dipicolinamide‐Based Push–Pull π‐Conjugated Systems as Nonreciprocal Circularly Polarized Luminescence Emitters

Chemistry – A European Journal, EarlyView.
This work presents the synthesis and characterization of chiral dipicolinamide push–pull fluorophores. While possessing similar photophysical properties in solution, their solvent‐annealed thin films exhibit unexpected, nonreciprocal chiroptical activity in both absorption and emission, including a complete inversion of the chiroptical profile upon ...
