been proposed to proceed via a polar pathway, an initial single-electron transfer pathway and an initial hydrogen atomtransfer pathway. Results from previous studies on selected N-cyclopropyl-4-substituted-1,2,3,6-tetrahydropyridine derivatives have led us to consider a mechanism for these cyclic tertiary allylamines which may not necessarily involve the aminyl radical cation as required by an initial

supramolecular peptide amphiphile (SPA) and its vesicular aggregates is displayed. The construction of the amphiphile is assisted by the ternary complexation of cucurbit[8]uril and pH responsive imine bond formation. The transient assembly follows a pH clock set by urea/urease and hydrolysis of glucono delta-lactone (GdL). The transient assembly can be repeated for several cyclesthrough feeding the system

Noncovalent synthesis of stable heterostructures (graphene-BN, MoS2-graphene) of layered materials has been accomplished by a ternary host–guest complex as a heterocomplementary supramolecular motif. Besides being reversible, this supramolecularstrategy to generate heterostructures may find uses in many situations.
A series of viologen-based receptors have been synthesized and their anion-binding properties have been investigated by-NMR, UV-visible spectroscopy, electrochemistry and X-ray diffraction analyses. Linking two positively charged viologens through a propyl chain promotes a remarkable chelate-like binding of chlorides revealed by 1H-NMR spectroscopy. Of all the anionic species investigated, only fluoride is detectable by the naked eye and by electrochemical methods. The reduction-triggered formation of a π-dimer from two viologen-based cation radicals was also investigated by electrochemical and spectroelectrochemical methods and by theoretical calculations.
