As a point of reference, the current performance of our easy-to-process polymers already exceeds that of amorphous silicon, which is the material most commonly used in the backplane of liquid crystal displays. We research ways in which this can be optimised and how to improve these materials even further (4). As a consequence, what limits the performance of these novel materials is the necessary hopping of charges between polymer chains. These materials can be imagined like graphene-tape, wherein charges can move efficiently along individual chains. Our group has made several pioneering breakthroughs in understanding the fundamental physical mechanisms in organic semiconductors (1,2,3). One example is a recent breakthrough in developing a printable polymer, in which the natural disorder of individual chains is overcome by a planar and torsion-free polymer backbone.

Our work has had some impact on the commercialisation of this technology: we collaborate with industrial partners (such as Flexenable Ltd.) to identify and address new requirements and material needs. We work with organic chemists to develop new and better materials and understand their structure-property relationships. To enable such technologies we work on understanding the charge transport physics of the organic semiconductor materials and we aim to understand the fundamental charge transport processes of these unusual systems in as much microscopic detail as possible.

It might also make possible soft, stretchable bioelectronic circuits that can be used in direct contact with human skin to monitor personal health conditions or deliver medial treatments. This may enable the fabrication of novel electronic devices, such as flexible displays for mobile phones or displays integrated into a wide range of everyday objects, including clothing. The main attribute of organic materials for these applications is their soft, flexible nature and the ability to print them at low cost over large areas. Over the past two decades, solution-processed organic semiconductors have developed into an attractive class of materials for use in flexible and large-area electronic technologies.
