Host–guest complexes with tuneable solid state structures [PDF]

Chemical Communications, 2000
Molecular clip receptors with long hydrocarbon tails self-assemble and form lamellar thin solid films, the architecture and properties of which can be fine-tuned by complexation of guest molecules.

Encapsulation in Charged Droplets Generates Distorted Host‐Guest Complexes**

Chemistry – A European Journal, 2023
AbstractThe ability of various hydrogen‐bonded resorcinarene‐based capsules to bind α,ω‐alkylbisDABCOnium (DnD) guests of different lengths was investigated in solution and in the gas‐phase. While no host‐guest interactions were detected in solution, encapsulation could be achieved in the charged droplets formed during electrospray ionisation (ESI ...

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

Advanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Inclusion of Hydroxycinnamic Acids in Methylated Cyclodextrins: Host-Guest Interactions and Effects on Guest Thermal Stability

Biomolecules, 2020
There is ongoing interest in exploiting the antioxidant activity and other medicinal properties of natural monophenolic/polyphenolic compounds, but their generally low aqueous solubility limits their applications. Numerous studies have been undertaken to

Halide‐Dependent Photoluminescence and Heavy‐Atom Effects in Low‐Melting Organic–Inorganic Manganese Halides

Advanced Functional Materials, EarlyView.
Two pyridinium‐based ionic liquid templated hybrid manganese halides, (C4Py)2[MnCl4] and (C4Py)2[MnBr4], display similar bulk structures but show significantly different photoluminescence behaviors due to the bromine heavy‐atom effect. Their stable local Mn environments remain intact even in the molten state, allowing applications such as luminescence ...
