Welcome to the Beer Group! Research in the Beer Group aims to increase understanding of molecular recognition processes in biological systems, leveraging that understanding to produce new molecular sensors, switches and devices.
This is achieved via the synthesis of novel macrocyclic and interlocked hosts which are designed to complex cationic, anionic or neutral guest species, reporting the binding via redox- or photo-active moieties. Designing selective binding of specific guest species is paramount, with anion-templated and halogen bonding-directed motifs particularly being pursued by the group towards this goal.

Inspired by the strong and highly selective binding of sulfate and phosphate anions in nature, achieved via a network of hydrogen bonds buried deeply inside specific proteins, we have pioneered an innovative, strategic anion templation methodology that has significantly advanced the construction of sophisticated hosts containing three dimensional cavities for anion recognition. This method uses anionic species to template the assembly of interpenetrating and interlocked host molecules.
Shown below is our initial anion templated pseudo-rotaxane along with the crystal structure. It can be seen that the assembly of the pseudo-rotaxane occurs through binding of a chloride anion template via hydrogen bonding in an orthogonal manner. Secondary aromatic donor-acceptor π-stacking interactions between the electron-rich hydroquinones of the macrocycle and the electron-deficient pyridinium thread, and hydrogen bonding between the polyether chain and the methyl group of the pyridinium cation also contribute to the stability of the interpenetrative assembly.
The strength of this general anion templation procedure was first illustrated with the chloride anion templated assembly of the first rotaxane and catenane interlocked anion host molecules. An impressive feature of this method of mechanical bond formation is that the resultant interlocked molecular structure retains a degree of functionality based on the anion template itself. After template removal, the unique interlocked cavities of the superstructures exhibit a high degree of selectivity for the templating chloride anion, in preference to competing basic oxoanions, which are too large, with unfavourable geometry to penetrate the binding pocket (see example below). The power of this anion templation methodology has since been exploited with chloride, bromide, sulfate, nitrate and nitrite templated synthesis of a range of rotaxane and catenane host structures containing convergent hydrogen bond donating cavities.

A variety of electrochemical and optical reporter groups have been incorporated into interlocked anion host constructs, with the aim of developing sophisticated chemical sensor technologies.
Transition metal and lanthanide luminophores, (see structure below), as well as organic fluorophores have been integrated into either the macrocyclic or axle stoppering components of rotaxanes and catenanes, which have been demonstrated to exhibit highly selective optical sensing of anions in solution.
Electrochemical sensing has been achieved with redox-active ferrocene functionalised rotaxanes and catenanes, in which anion binding caused cathodic perturbations of the ferrocene/ferrocenium redox-couple. In a first step towards the development of practical sensory devices, the anion templation strategy has been applied to the fabrication of redox-active ferrocene and osmium (II) bipyridyl functionalised rotaxane and ferrocene functionalised catenane self-assembled monolayers (SAMs) on to gold electrode surfaces. The rotaxane SAM interlocked host binding domains were demonstrated to be capable of selectively sensing chloride anions electrochemically.

Halogen bonding (XB) is the non-covalent bonding interaction between halogen atoms which function as electrophilic centres (Lewis acids) and neutral or anionic Lewis bases. Of the many non-covalent interactions commonly utilized in solution phase supramolecular assemblies, halogen bonding is arguably the least exploited, which is surprising given its potentially powerful analogy to ubiquitous hydrogen bonding (HB). We have reported the first examples of solution phase halogen bonding being exploited to recognize and sense anions in aqueous media, and to control and facilitate the anion templated assembly of rotaxane and catenane interlocked structures (see figure below), including a molecular shuttle.
Importantly, the incorporation of halogen bond donors into acyclic, macrocyclic, and interlocked host cavities dramatically enhances anion recognition compared to hydrogen bond donor host analogues in aqueous media. For instance, we recently demonstrated the exploitation and quantification of XB in water for the first time using water-soluble acyclic and rotaxane hosts prepared from mono-functionalised permethylated β-cyclodextrin derivatives. Incorporation of XB-donors into such receptors resulted in a dramatic enhancement of anion binding in water compared to the equivalent HB analogues, with up to two orders of magnitude enhancement observed in the interlocked XB rotaxane host system (see figure below).
In collaboration with Professor Pierre Kennepohl (University of British Columbia), we have also investigated the nature of halogen bonds through X-ray Absorption Spectroscopy (XAS): these studies revealed charge transfer from the halide to its halogen bonding partner, and demonstrated that the degree of covalency is similar to that which is observed in transition metal coordinate covalent bonds.
These results highlight the superiority of XB as an intermolecular interaction for anion binding in water, and exemplify the exciting potential of XB in other applications requiring molecular assembly in aqueous environments that have been traditionally dominated by the ubiquitous hydrogen bond, including self-assembly, green-chemistry, catalysis and drug discovery.

Mechanically interlocked molecules (MIMs) are firmly established entities in the field of nanoscale molecular machines, being able to undergo controlled and reversible molecular motion by changes in the relative positions of their constituent parts. Through careful design, the inherent dynamics of such systems may be governed by a variety of stimuli. Our group explores co-conformational switching mediated by the recognition of anionic species, an underexplored area, as a means of generating detectable responses for use in sensing.
The incorporation of a naphthalimide–triazolium derivative into an axle component produced a bistable rotaxane in which the position of the macrocyclic wheel could be controlled upon cooperative binding of chloride within the rotaxane’s cavity as shown below.
The contrasting halide recognition properties of hydrogen-bonding (HB) proto- and halogen bonding (XB) iodo-triazolium motifs has been used as a basis for a two-station rotaxane molecular switch. In the system below, chloride anion binding resulted in occupation of the HB station whilst macrocycle shuttling to the XB station occurred upon the addition of iodide.
Quantitative analysis of station occupancies has allowed a detailed comparison of the halide-induced translational motion produced by a series of two-station XB- and HB-triazolium–naphthalene diimide rotaxanes (see below). The system incorporating a XB donor anion recognition site was demonstrated to exhibit superior macrocycle shuttling relative to the HB analogue courtesy of strong XB–chloride anion binding interactions.
Through the integration of photo- and/or redox-active reporter groups into two station MIMs, the dynamic co-conformational changes resulting from anion guest recognition can be utilised as a unique mechanism for sensing negatively charge species, shown schematically below.
This concept has been demonstrated with the construction of an exotic XB rotaxane four-station molecular shuttle that is capable of the colorimetric sensing of oxoanions, in particular nitrate, courtesy of novel pincer-like motion of the two macrocycle components that occurs upon binding. Importantly, this is also the only synthetic interlocked receptor capable of selectively recognising the environmentally important nitrate anion over other oxoanion species and chloride.

This exciting area of coordination chemistry is concerned with the synthesis of host molecules containing binding sites for anionic and cationic guest species, covalently linked together and fashioned to be selective for target alkali/transition metal salts or zwitterionic guests such as amino acids. The simultaneous binding of toxic/radioactive ion-pair species could make these systems novel extraction reagents for the purification of industrial effluent, soil water and radioactive waste streams.
A recent highlight in this area is the demonstration of an unprecedented cooperative "AND" ion-pair recognition phenomenon in which the heteroditopic calixdiquinone rotaxane-based receptor shown below displays no binding affinity for either individual cation or anion, but binds the cation AND anion ion-pair strongly.

The dithiocarbamate (dtc) ligand has been exploited in the metal directed assembly of a variety of novel macrocycles, cryptands, catenanes and nano-sized polymetallic host systems. A particular highlight includes the synthesis of nano-sized molecular loops based on a trimer of resorcarene functionalised dtc ligands assembled by six zinc (II) or cadmium (II) ions and tetrahedra constructed by eight copper (II) or copper (III) ions (shown below). The hexanuclear zinc and cadmium "molecular loop" and octanuclear copper "cagelike" polymetallic structures were subsequently found to strongly bind fullerenes C60 and C70.
In addition a mixed valence tetranuclear copper(II)/copper(III) dithiocarbamate catenane was prepared by partial chemical oxidation of a preformed dinuclear copper (II) dtc napthyl spaced macrocycle, where the lability of the copper(II) dtc coordinate bonds together with favourable charge transfer stabilisation effects are responsible for the near quantitative yield of the interlocked structure.
Recently we reported the first lanthanide cation template-directed assembly of an interlocked structure, by preparing lutetium and europium templated rotaxanes. An initial interpenetrated assembly is formed between a pyridine N-oxide threading component coordinating to a lanthanide cation complexed within a macrocycle, and a subsequent "click" stoppering reaction forms the rotaxane interlocked product.
