Mechanically interlocked molecular handcuffs (2022)
Journal Article

The field of mechanically interlocked molecules that employ a handcuff component are reviewed. The variety of rotaxane and catenane structures that use the handcuff motif to interlock different components are discussed and a new nomenclature, distill...

The chemistry of phosphines in constrained, well-defined microenvironments (2021)
Journal Article

Developments in the confinement of phosphines within micro- or nano-environments are explored. Phosphines are ubiquitous across metal coordination chemistry and underpin some of the most famous homogeneous transition metal catalysts. Constraining pho...

Metal-Organic Frameworks and Metal-Organic Cages – A Perspective (2020)
Journal Article

© 2020 Wiley-VCH GmbH The fields of metal-organic cages (MOCs) and metal-organic frameworks (MOFs) are both highly topical and continue to develop at a rapid pace. Despite clear synergies between the two fields, overlap is rarely observed. This artic... Read More about Metal-Organic Frameworks and Metal-Organic Cages – A Perspective.

Dynamic pH responsivity of triazole-based self-immolative linkers (2020)
Journal Article

Gating the release of chemical payloads in response to transient signals is an important feature of ‘smart’ delivery systems. Herein, we report a triazole-based self-immolative linker that can be reversibly paused or slowed and restarted throughout i...

Multivalent Crown Ether Receptors Enable Allosteric Regulation of Anion Exchange in an Fe4L6 Tetrahedron (2018)
Journal Article

We report a strategy for regulating the rate of internally bound anion exchange within an Fe4L6 metal–organic tetrahedron through external coordination of tripodal tris(alkylammonium) cations. The cage features three flexible 18‐crown‐6 receptors at... Read More about Multivalent Crown Ether Receptors Enable Allosteric Regulation of Anion Exchange in an Fe4L6 Tetrahedron.

Covalent Post-assembly Modification Triggers Multiple Structural Transformations of a Tetrazine-Edged Fe4L6 Tetrahedron (2018)
Journal Article

Covalent post-assembly modification (PAM) reactions are useful synthetic tools for functionalizing and stabilizing self-assembled metal–organic complexes. Recently, PAM reactions have also been explored as stimuli for triggering supramolecular struct...

Signal transduction in a covalent post-assembly modification cascade (2017)
Journal Article

Natural reaction cascades control the movement of biomolecules between cellular compartments. Inspired by these systems, we report a synthetic reaction cascade employing post-assembly modification reactions to direct the partitioning of supramolecula...

Pathway-Dependent Post-assembly Modification of an Anthracene-Edged MII4L6 Tetrahedron (2016)
Journal Article

FeII4L6 tetrahedral cage 1 undergoes post-assembly modification (PAM) via a Diels–Alder cycloaddition of the anthracene panels of the cage with tetracyanoethylene (TCNE). The modified cage 2 possesses an enclosed cavity suitable for encapsulation of... Read More about Pathway-Dependent Post-assembly Modification of an Anthracene-Edged MII4L6 Tetrahedron.

Perfluorinated Ligands Induce Meridional Metal Stereochemistry to Generate M8L12, M10L15, and M12L18 Prisms (2016)
Journal Article

FeII4L6 tetrahedral cage 1 undergoes post-assembly modification (PAM) via a Diels–Alder cycloaddition of the anthracene panels of the cage with tetracyanoethylene (TCNE). The modified cage 2 possesses an enclosed cavity suitable for encapsulation of...

Post-assembly Modification of Tetrazine-Edged FeII4L6 Tetrahedra (2015)
Journal Article

Post-assembly modification (PAM) is a powerful tool for the modular functionalization of self-assembled structures. We report a new family of tetrazine-edged FeII4L6 tetrahedral cages, prepared using different aniline subcomponents, which undergo rap...

Short and Efficient Syntheses of Protoberberine Alkaloids using Palladium-Catalyzed Enolate Arylation (2014)
Journal Article

A concise synthesis of the biologically active alkaloid berberine is reported, and a versatile palladium?catalyzed enolate arylation is used to form the isoquinoline core. The overall yield of 50?% is a large improvement over the single, previous syn... Read More about Short and Efficient Syntheses of Protoberberine Alkaloids using Palladium-Catalyzed Enolate Arylation.
