Crystal engineering of alkylethynyl fluoroanthradithiophenes
2-Dimensional brickwork packing is desirable for high mobility organic semiconductors. We synthesised acene derivatives that adopt this packing without using heavier group 14 elements to investigate substituent effects on bulk transport properties.

Conjugated polyelectrolyte-based ternary exciton funnels via liposome scaffolds
We used a vesicle scaffold to form a ternary, quasi-panchromatic funnel for electronic excited states oriented from the outer surface towards the membrane. We did so via electronic energy transfer (EET) from two conjugated polyelectrolytes to a phthalocyanine.

Development of hybrid coarse-grained atomistic models for rapid assessment of local structuring of polymeric semiconductors
A model of semiconducting polymers where the conjugated portion is described with atomistic detail and the alkyl side chains are approximated with a coarse grain potential is very promising for the molecular design of new polymeric materials.
