"A quick and easy way to tune the photoluminescence and electrical conductivity of promising organic polymers opens the door to innovation for all sorts of optical, electronic, and optoelectronic applications."
The article includes the main results achieved by the project regarding the modification of the properties of PEDOT, a well-known conductive organic polymer.
"Viñas’s research produced impressive results. She demonstrated a simple and efficient way to achieve tuning by focusing on the accompanying cations of the doping anions, which determine the stoichiometries of the COPs that, in turn, influence the electrochemical properties. This outcome was featured on the cover of ‘Chemistry – A European Journal’.
While investigating the intended use of metallacarboranes as tuneable doping anions, Viñas also serendipitously discovered their photoredox catalytic property and apparent thermoelectrical capacity. Experimental and computational studies of metallacarboranes led to papers regarding photoluminescence in bivalent and trivalent metallacarboranes."
“It was exciting to find that, after so many years of COPs research, something as trivial as the accompanying cation – usually considered innocent, or having a clear and predictable oxidation state – was able to modify the stoichiometry of the conducting polymer and alter its physicochemical properties,” says Viñas.

About CORDIS "Results in brief" section
CORDIS provides the publication of the project results as part of the European Commission's strategy on the dissemination and exploitation of research results. Communication about the project is a contractual obligation, and this is a good opportunity to communicate the results of a project so the public can see the benefit of the EU's science investment. Around 80 articles of selected projects are published on a monthly basis.
