The effect of number and position of P=O/P=S bridging units on cavitand selectivity toward methyl ammonium salts.
The present work reports the synthesis and complexation properties of five mixed bridge P=O/P=S cavitands toward N,N-methyl butyl ammonium chloride (1) as prototype guest. The influence of number and position of P=O and P=S groups on the affinity of phosphonate cavitands toward 1 is assessed via ITC titrations in DCE as solvent. Comparison of the resulting Kass values, the enthalpic and entropi...
متن کاملHalogen-bonded solvates of tetrahaloethynyl cavitands†
Halogen bonding (XB) has been receiving considerably increasing attention as it provides a complementary interaction to hydrogen bonding (HB). XB has been proven to play crucial roles in supramolecular chemistry, nanoscience, biosystems, and functional materials. Its directionality and tunability make XB an important noncovalent interaction, geometrically and thermodynamically, similar to HB; h...
متن کاملGrafting cavitands on the Si(100) surface.
Cavitand molecules having double bond terminated alkyl chains and different bridging groups at the upper rim have been grafted on H-terminated Si(100) surface via photochemical hydrosilylation of the double bonds. Pure and mixed monolayers have been obtained from mesitylene solutions of either pure cavitand or cavitand/1-octene mixtures. Angle resolved high-resolution X-ray photoelectron spectr...
متن کاملMetallocyclodextrins: Combining Cavitands with Metal Centres
In the last decades, combining the properties of a transition-metal ion with those of a covalently linked, molecular cavity has attracted a great deal of attention. Numerous studies focused on the design and synthesis of systems exploiting the binding properties of a receptor moiety attached to an active metal site, with the aim of mimicking nature’s metal-containing catalysts: metalloenzymes. ...
متن کاملDeep cavitands featuring functional acetal-based walls.
The synthesis of deep cavitands with functionalized acetals as a fourth-wall is described. Recognition properties and stabilities of the complexes of two representative cavitands with aliphatic, aromatic, carbocyclic and adamantane guests were evaluated by NMR methods.
