Shining a light on the photo-sensitisation of organic-inorganic hybrid polyoxometalates (2018)
Journal Article

Finding new ways of using visible light (or, more specifically, solar irradiation) to drive commercially significant and/or challenging chemical processes is an ongoing research goal. Polyoxometalates (POMs) are discrete, metal-oxide clusters which a... Read More about Shining a light on the photo-sensitisation of organic-inorganic hybrid polyoxometalates.

A Simple Approach to the Visible-Light Photoactivation of Molecular Metal Oxides (2017)
Journal Article

© 2017 American Chemical Society. This study explores a new method to maximize the visible-light-driven photocatalytic performance of organic-inorganic hybrid polyoxometalates (POMs). Experimental and theoretical investigations of a family of phospho... Read More about A Simple Approach to the Visible-Light Photoactivation of Molecular Metal Oxides.

Synthesis, crystal structures and magnetic properties of composites incorporating an Fe(II) spin crossover complex and polyoxometalates (2017)
Journal Article

[Fe(dppOH)2]2+ (dppOH = 2,6-di(pyrazol-1-yl)-4-(hydroxymethyl)pyridine) is known to show spin crossover (SCO) behavior and light-induced excited spin state transitions (LIESST). Here, we show that the SCO properties of the [Fe(dppOH)2]2+ complex can...

Orbital engineering: photoactivation of an organofunctionalized polyoxotungstate (2016)
Journal Article

Tungsten-based polyoxometalates (POMs) are employed as UV-driven photo-catalysts for a range of organic transformations. Their photoactivity is dependent on electronic transitions between frontier orbitals, and thus manipulation of orbital energy lev...
