PRESENTATION TITLE: Spectroelectrochemistry of Conjugated Polymers: Bridging the Gap.

ABSTRACT
Conjugated polymers are a type of molecular material that will play a very relevant role in several technological fields currently under huge development. These polymers are intrinsic semiconductors in native state which allows them to be used as replacements for classic inorganic compounds (such as silicon) in electronic devices such as photovoltaic cells (OPV), light-emitting diodes (OLED) or organic transistors (OFET). Their controllable optoelectronic properties, together with their plastic character have permitted the development of a new high-impact discipline called “organic electronics”. Another important characteristic of these polymers is the dramatic change of their properties when they are doped (usually by electrochemical reactions). One of the most useful tools for the development of the applications of these polymers are a set of spectroscopic techniques (such as UV-vis, FT-IR or fluorescence) that can be coupled to a control of the electrochemical state of the polymer, the so-called spectroelectrochemical technique. The in situ monitoring of optoelectronic properties of the polymer allows the optimization of their applications as synthetic metals, electrochromic devices, artificial muscles or electrochemical biosensors (for “wet” devices). Additionally, these techniques are powerful tools to understand key parameters on the functioning of these conjugated polymers in “dry” optoelectronic devices, such as exciton dynamics, carrier mobility and recombination kinetics.

ABOUT THE PRESENTER
Francisco Montilla is Associate Professor since 2011 in the Group of Electrocatalysis and Polymer Electrochemistry at the University of Alicante (https://orcid.org/0000-0003-4769-9130). He has performed research in several topics ranging from basic to applied electrochemistry. During his PhD, he synthesized dimensionally stable anodes for the abatement of pollutants in wastewater. During post-doc stages at the Universidad Miguel Hernández (Spain) and University of St. Andrews (UK) he conducted research on conjugated polymers, developing a novel spectroelectrochemical technique (in situ fluorescence or electrofluorochromism). His most recent research is focused on the development of modified electrodes for biosensors and direct electrochemistry of proteins.
