FRIAS Project
Orienting semi-crystalline conjugated polymers through dewetting and nucleation control.
Low cost solution processing coupled with high-performance opto-electronic properties make semi-crystalline π-conjugated polymers key materials in the development of organic electronic technology such as transistors, light emitting diodes and photovoltaic cells.
The aim of this project is to generate model systems comprising large arrays of oriented and partially crystalline domains of semiconducting polymers like polythiophenes. The formation of large aligned domains will allow establishing detailed and predictive correlations between specific aspects of molecular order and opto-electronic properties. In view of a potential applicability, we intend to obtain such model systems by developing approaches based on dewetting and self-organization processes. Our central goal is to unveil the underlying physical processes both concerning the ordering processes and the resulting electronic properties of such oriented polymer structures. To this end, we will develop pathways to control the kinetics of molecular organization and the degree of order, based on techniques like dewetting, nucleation and growth and related self-organization processes controlled via appropriate deformation of the polymeric chains (e.g. by rubbing or stretching) and directed by specific interactions with appropriate substrates.
