“…Curiously enough, the second, presumably thermodynamic, polymorph of bis-(ferrocenyl-telluride) (Fc 2 Te 2 (ref. 43)) was obtained under conditions similar to those of 1β – upon the decomposition of [Mo(CO) 5 ](Fc 2 Te 2 ) during the crystallization from DCM/hexane. As a matter of fact, there are also reported cases of polymorphism for a number of diaryl ditellurides like bis-(2-naphthyltelluride), 44 bis-( p -tolyl-telluride), 45 bis-( p -chlorophenyltelluride), 45 and bis-( p -bromophenyltelluride).…”

“…The novel ChB bis(ferrocene-telluro-triazole) receptor 2.Te was constructed by direct appendage of ferrocene (Fc) redox reporters onto an established bis(tellurotriazole) anion receptive scaffold (Scheme ). ,, This was achieved by reaction of pyridine bis(silveracetylide) 3 with in situ generated ferrocenyl tellurobromide, obtained from reaction of diferrocenyl ditelluride with bromine, affording 3,5-pyridine bis(ferrocenylalkyne) 4 . This compound was immediately subjected to copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with two equivalents of azido pentafluorobenzene affording the title compound 2.Te in 54% yield over two steps .…”

Inspired by the success of its related sigma-hole congener halogen bonding (XB), chalcogen bonding (ChB) is emerging as a powerful noncovalent interaction with a plethora of applications in supramolecular chemistry and beyond. Despite its increasing importance, the judicious modulation of ChB donor strength remains a formidable challenge. Herein, we present, for the first time, the reversible and large-scale modulation of ChB potency by electrochemical redox control. This is exemplified by both the switching-ON of anion recognition via ChB oxidative activation of a novel bis(ferrocenyltellurotriazole) anion host and switching-OFF reductive ChB deactivation of anion binding potency with a telluroviologen receptor. The direct linking of the redox-active center and ChB receptor donor sites enables strong coupling, which is reflected by up to a remarkable 3 orders of magnitude modulation of anion binding strength. This is demonstrated through large voltammetric perturbations of the respective receptor ferrocene and viologen redox couples, enabling, for the first time, ChB-mediated electrochemical anion sensing. The sensors not only display significant anion-binding-induced electrochemical responses in competitive aqueous-organic solvent systems but can compete with, or even outperform similar, highly potent XB and HB sensors. These observations serve to highlight a unique (redox) tunability of ChB and pave the way for further exploration of the reversible (redox) modulation of ChB in a wide range of applications, including anion sensors as well as molecular switches and machines.
