The inhibition of iridium-promoted water oxidation catalysis (WOC) by cucurbit[n]urils.
A series of iridacycles bearing π-bonded moieties of variable electron-withdrawing capabilities were tested for their ability to promote water oxidation catalysis (WOC) in the presence of high loading in a sacrificial oxidant, under conditions chosen for optimal dioxygen production. This report shows that none of these complexes performs differently than monometallic iridacycles and that the π-...
متن کاملRaman and SERS spectroscopy of cucurbit[n]urils.
Cucurbit[n]urils (CB[n]) are a family of supramolecular hosts which can provide highly selective recognition based on their size (n). In this work we study their Raman spectroscopic signatures both experimentally and by molecular simulation and find systematic trends providing evidence of ring strain effects with size. Furthermore, we present for the first time their surface-enhanced Raman scat...
متن کاملThe potential of cucurbit[n]urils in drug delivery
In this paper we review cucurbit[n]urils (CB[n]), a relatively new family of macrocycles that has shown potential in improving drug delivery. Encapsulation of drugs within the homologues CB[6], CB[7] or CB[8] can impart enhanced chemical and physical stability, improve drug solubility and control drug release. The formulation of CB[n] into a dosage form suitable for clinical use is a non-trivia...
متن کاملStimuli-responsive supramolecular micellar assemblies of cetylpyridinium chloride with cucurbit[5/7]urils.
This article demonstrates, for the first time, construction of novel cucurbituril (CB)-adorned supramolecular micellar assemblies of a cationic surfactant, cetylpyridinium chloride (CPC), through noncovalent host-guest interactions. The distinct cation receptor features and cavity dimensions of the CB5 and CB7 homologues assert that the macrocyclic hosts remain complexed with the CPC monomers a...
متن کاملModulating the Nucleated Self-Assembly of Tri-β(3) -Peptides Using Cucurbit[n]urils.
The modulation of the hierarchical nucleated self-assembly of tri-β(3) -peptides has been studied. β(3) -Tyrosine provided a handle to control the assembly process through host-guest interactions with CB[7] and CB[8]. By varying the cavity size from CB[7] to CB[8] distinct phases of assembling tri-β(3) -peptides were arrested. Given the limited size of the CB[7] cavity, only one aromatic β(3) -...
