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.

Light, Redox, and Ligand Noninnocence Cooperate in Naphthalene Diimide‐Functionalized N‐Heterocyclic Carbene Iridium Complexes

Chemistry – A European Journal, EarlyView.
Naphthalene diimide–N‐heterocyclic carbene iridium complexes display uncommon multistimuli‐responsive behavior combining strong Cl(lp)···π interactions, ligand non‐innocence, visible‐light photoreduction, and conPET photocatalysis. The study also provides new insight into the interaction of NDI platforms with fluoride/basic anions, revealing unexpected

A Naphthalene Monoimide Meisenheimer Complex as Strong Organic Hydride Donor for Metal‐Free CO2 Reduction

Chemistry – A European Journal, EarlyView.
A Meisenheimer complex derived from two‐fold reduction and protonation of naphthalene monoamide has been identified as a strong organic hydride donor which is able to reduce CO2. ABSTRACT Selective CO2 reduction to formate is challenging due to similar thermodynamics for the reaction to other products such as carbon monoxide and molecular hydrogen ...

Regioisomerism Rewires Optical and Ion Recognition Properties in Azulenylsumanenes—Curved Non‐Alternant π‐Systems

Chemistry – A European Journal, EarlyView.
Regioisomerism rewires orbital topology and electronic polarity in curved non‐alternant π‐systems, switching both optical response and alkali metal ion recognition from Na+ to Rb+ selectivity. ABSTRACT Herein, we explore the fundamental concept of combining the molecular curvature of a molecular fragment of buckminsterfullerene with the pronounced ...
