Journal ArticleDOI
Circularly-Polarized Electrochemiluminescence from a Chiral Bispyrene Organic Macrocycle.
Francesco Zinna,Silvia Voci,Lorenzo Arrico,Elodie Brun,Alexandre Homberg,Laurent Bouffier,Tiziana Funaioli,Jérôme Lacour,Neso Sojic,Lorenzo Di Bari +9 more
TL;DR: The first observation of circular polarization of electrochemiluminescence (ECL) from a purely organic derivative is reported and is the first step towards the molecular engineering of tailored dyes that can act as both ECL and CP-ECL reporters for (bio)analysis.
Journal ArticleDOI
Combined reversible switching of ECD and quenching of CPL with chiral fluorescent macrocycles.
Alexandre Homberg,Elodie Brun,Francesco Zinna,Simon Pascal,Marcin Górecki,Luc Monnier,Céline Besnard,Gennaro Pescitelli,Lorenzo Di Bari,Jérôme Lacour +9 more
TL;DR: A series of chiral fluorescent macrocycles display a remarkable combination of both +/– ECD and strong on/off CPL reversible switching upon cation binding and displacement.
Journal ArticleDOI
Kinetics of Rh(II)-Catalyzed α-Diazo-β-ketoester Decomposition and Application to the [3+6+3+6] Synthesis of Macrocycles on a Large Scale and at Low Catalyst Loadings
TL;DR: In this paper, precise kinetics of α-diazo-β-ketoester decomposition were measured by in situ infrared (IR) monitoring, and Dirhodium complexes of the Ikegami-Hashimoto type and perchlorinated phthalimido derivatives performed better than classical achiral complexes.
Journal ArticleDOI
Efficient Synthesis of Ditopic Polyamide Receptors for Cooperative Ion Pair Recognition in Solution and Solid States.
TL;DR: Following a late-stage functionalization strategy, a series of heteroditopic cryptand receptors were prepared in three steps only from 1,4-dioxane, and present general ion pair binding capacity towards salts of monovalent cations and linear triatomic anions.
Journal ArticleDOI
Excimer-Based On-Off Bis(pyreneamide) Macrocyclic Chemosensors
Mahesh Vishe,Timothée Lathion,Simon Pascal,Oleksandr Yushchenko,Alexandre Homberg,Elodie Brun,Eric Vauthey,Claude Piguet,Jérôme Lacour +8 more
TL;DR: A series of bis(pyreneamide) macrocycles, synthesized in two steps from THF, THP, oxepane and 1,4-dioxane, are tested as chemosensors for a large range of mono-, di- and trivalent cations as discussed by the authors.
