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 ...

Chemistry – A European Journal, EarlyView.Europium doping of bismuth oxido nanoclusters (BiO‐NCs) provides stable hosts for Eu3+ in an asymmetric coordination environment, which in turn results in an intense 5D0→7F0 transition and long luminescence lifetimes. Transparent hybrid materials showing characteristic red photoluminescence are accessible via radical copolymerisation of these soluble ...

Ionization energies of lanthanides
, 2010 This article describes how data are used to analyze the pattern of ionization energies of the lanthanide elements. Different observed pathways of ionization between different ground states are discussed, and the effects of pairing, exchange, and orbital ...

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.

Chemistry – A European Journal, EarlyView.The two Eu(III) complexes of 1.Eu and 2.Eu, that were formed in situ, were used to bind to yeast RNA and A10 (RNA) in a buffered pH 7 solution. The interaction gave rise to changes in the lanthanide‐centered emission because of direct binding of these complexes, which resulted in aggregation of the RNA, as demonstrated using phase‐contrast and atomic ...

Chemistry – A European Journal, EarlyView.Systematic studies of a series of new 3d–4f tetranuclear complexes revealed that the ferromagnetically coupled [Mn3Gd] complex exhibits large magnetic entropy changes, especially at higher temperatures and under lower magnetic fields. ABSTRACT A series of 3d‐4f heterometallic tetranuclear complexes, (TEA)[Mn3Gd(L)3(NO3)4(CH3CN)2] ([Mn3Gd]), (TEA)[Mn3La(
