Abstract:
The topologies of molecules and materials can have profound influence over their resulting properties. Synthetic chemists have been attempting for decades to control topology - that is, the manner is which molecules are entangled or interwoven - with limited success. Our recent work has demonstrated metal-ion template structures such as cyclic helicates and grids are ideal for forming more complex topologies, and offer new routes for increasingly complicated assemblies. The first synthesis of a molecular pentafoil knot, and efficient routes molecular links will be presented.

The use of Ru(II) polypyridyl complexes as dyes for light harvesting, or more recently as visible light photoredox catalysts has become widespread. Our current efforts to incorporate this useful functionality into molecular receptors and cages will be presented.

Short CV:
Jon obtained his BSc (Hons) (2002) and MSc (2004) from the University of Sydney, under the supervision of Prof Len Lindoy FAA, before moving to Basel (Switzerland) for his PhD under the joint supervision of Prof Ed Constable and Prof Catherine Housecroft. From 2009-2012 he was a Swiss National Science Foundation Post-doctoral Fellow at the University of Edinburgh (UK) under the supervision of Prof David A. Leigh FRS. From March 2012 - February 2013 he was Research A/Prof at Nanjing University (China). In March 2013 he commenced his current position at UNSW. Jon's research interests cover much of supramolecular and applied coordination chemistry, ranging from crystal engineering to molecular sensors, light-switchable molecular devices and machines.
