Asymmetric Ligand Field Effects in Electron‐Rich Heterometallic Extended Metal Atom Chain Compounds

Chemistry – A European Journal, EarlyView.
Synthesis of multimetallic compounds with modifiable scaffolding ligands raises questions about the distribution of electronic effects in heterometallic systems. Here we investigate the asymmetry of the substituent effects in a modified 2,2′‐dipyradylamine ligand applied to a heterotrimetallic extended metal atom chain (HEMAC) framework.

Targeting G‐Rich lncRNA and its Structural Polymorphism with Selective G‐Quadruplex Ligands: An NMR Study

Chemistry – A European Journal, EarlyView.
The REG1CP‐derived RNA oligonucleotide SL15P adopts a parallel G‐quadruplex (rGQ) structure. In this study, we investigate the effect of several well‐characterized ligands, originally developed for DNA GQs, on the RNA counterpart, with the aim of evaluating their binding ability and specific binding modes.

Path Selective Photoinduced Energy and Electron Transfer in a Bis(acridinium‐Zn(II) Porphyrin)‐tetrapyridyl Porphyrin Host‐Guest Complex

Chemistry – A European Journal, EarlyView.
Tuning unusual energy and eT processes in a bis(acridinium‐Zn(II) porphyrin)‐tetrapyridyl porphyrin host‐guest complex. Abstract The 1:1 complex of a bis(acridinium‐Zn(II)porphyrin) host and a tetrapyridyl free‐base porphyrin guest shows a remarkable interplay of energy and electron transfer (eT) processes, finely tuned by the solvent polarity or the ...
