Fullerenes are an exciting class of organic semiconductors that combine a high electron affinity and mobility. Mixing with suitable polymers facilitates the preparation of plastics that exploit this unique set of electronic properties.
In my talk I will discuss some of our recent work on polymer:fullerene blends for opto-electronic applications such as field-effect transistors and polymer solar cells. In particular, I will cover the use of fullerene mixtures, including both unsubstituted fullerenes as well as PCBMs, which opens up a toolbox that can be employed to control aspects such as solubility, glass formation and crystal nucleation.
In addition, I will introduce a new application area for fullerenes: voltage stabilizers for power cable insulation, which increase the dielectric strength of the insulation material. Such compounds are highly sought-after because their use in power cable insulation may considerably enhance the transmission efficiency of tomorrow’s power grids.
