Selective photoinduced charge separation in perylenediimide-pillar[5]arene rotaxanes (2022)
Journal Article

The ability to control photoinduced charge transfer within molecules represents a major challenge requiring precise control of the relative positioning and orientation of donor and acceptor groups. Here we show that such photoinduced charge transfer... Read More about Selective photoinduced charge separation in perylenediimide-pillar[5]arene rotaxanes.

Synthesis and characterisation of rylene diimide dimers using molecular handcuffs (2019)
Journal Article

A strategy for positioning, and loosely connecting, molecules in close proximity using mechanically interlocked handcuffs is described. The strategy is demonstrated using rylene diimides, creating dimeric structures in which two components are linked...

Selective reduction and homologation of carbon monoxide by organometallic iron complexes (2018)
Journal Article

Carbon monoxide is a key C1 feedstock for the industrial production of hydrocarbons, where it is used to make millions of tonnes of chemicals, fuels, and solvents per annum. Many transition metal complexes can coordinate CO2 but the formation of new... Read More about Selective reduction and homologation of carbon monoxide by organometallic iron complexes.

Influence of hydrogen-bonding interactions on nuclearity and structure of palladium tiara-like complexes (2018)

Self-assembly of chiral-at-end diketopyrrolopyrroles: symmetry dependent solution and film optical activity and photovoltaic performanace (2018)
Journal Article

Chiral thiophene-diketopyrrolopyrrole derivatives have been synthesised to investigate the potential of stereochemistry and symmetry as a means of modulating properties by influencing self-assembly of these purely organic materials. In particular, de... Read More about Self-assembly of chiral-at-end diketopyrrolopyrroles: symmetry dependent solution and film optical activity and photovoltaic performanace.

Characterisation of redox states of metal-organic frameworks by growth on modified thin-film electrodes (2018)
Journal Article

The application of metal-organic framework (MOF) materials in electrochemical and electrochromic devices remain rare. One of the main reasons for this is the inability to readily access their detailed electrochemistry. The inherent insolubility of th...

Heterobimetallic [NiFe] complexes containing mixedCO/CN− ligands: analogs of the active site of the [NiFe]hydrogenases (2018)
Journal Article

The development of synthetic analogs of the active sites of [NiFe] hydrogenases remains challenging and, in spite of the number of complexes featuring a [NiFe] center, those featuring CO and CN− ligands at the Fe center are under-represented. We repo... Read More about Heterobimetallic [NiFe] complexes containing mixedCO/CN− ligands: analogs of the active site of the [NiFe]hydrogenases.

Thionated naphthalene diimides: tuneable chromophores for applications in photoactive dyads (2017)
Journal Article

Varying the degree of thionation of a series of naphthalene diimide (NDI) and naphthalic imides (NI) phenothiazine dyad systems afford a systematic approach for tuning of the system’s donor-acceptor energy gap. Each dyad was compared to model NDI/NI... Read More about Thionated naphthalene diimides: tuneable chromophores for applications in photoactive dyads.

Core-substituted naphthalene diimides: influence of substituent conformation on strong visible absorption (2017)
Journal Article

Substitution of the aromatic core of naphthalene diimide (NDI) chromophores by morpholine leads to molecules with strong absorbance in the visible spectrum.
