Different items ar ediscusse dsuch as synthesis of conjugated polymers/molecules, electronic states, optical and electronic properties, material characterization and electronic devices (OLED, OFET, OPV, sensors....). Recent development on the consummer electronics realted evices are also discussed. AIMS AND CONTENT LEARNING OUTCOMES Basic knowledge of chemical and physical properties of molecular and polymer semiconductors. Working mechanisms for optoelectronic devices (sensors, OLED, OFET, OPV) AIMS AND LEARNING OUTCOMES Electronic properties of conjugated materials and their relations with chemical and sipramolecular properties. Main characterization techniques of conjugates materials. Spectroscopy and photophysics. Working principles for sensors, OFET, OLED, OPV and relation with material properties. TEACHING METHODS Combination of traditional lectures (50 hours) and preparation of simple experience/exercise SYLLABUS/CONTENT Lessons will deal with the following items: Extended p-electron systems both in molecules and polymers. Conjugation length: ionization potential, electron affinity and HOMO-LUMO gap in the series ranging from ethylene to polyene. [Electronic states for the polyene: the Huckel method for the isolated chain and for interacting macromolecules]. Dimerization and Peierls distorsion: metal and semiconducting polymers. Conducting conjugated polymers: doping and applications. Charge transport in semiconducting and conducting polymers. Spectroscopy of conjugated systems: [electronic transitions], Franck-Condon principle and [vibronic transitions], fluorescence and lifetime, singlet and triplet excitons, Jablonski diagram and photophysics. Synthesis of main conjugated polymer families (polyacetylene, polythiophene, poly(p-phenylenevinylene)). Functionalization of chemical and physical properties of conjugated materials (solubility, ionization potential, electron affinity). Supramolecolar structure of conjugated polymers and role of aggregation in the solid state. Orientation techniques of conjugated polymers, optical and electronic properties anisotropy. Working principles of devices made of conjugated molecules and polymers: sensors, devices for non-linear optics, OLED, PLED, OTFE, photovoltaic cells and light harvesting based devices. Role of the supramolecular structure on the main electronic properties and on devices. Practice: [Calculation of the electronic structure of 1D and 3D polyacetylene.] Preparation of conjugated polymer thin films by spin coating and drop casting. Transmission, reflection and fluorescence spectroscopy of conjugated polymers in solution (both liquid and solid) and at the solid state. LAB ACTIVITIES MIGHT DEPEND ON THE NUMBER OF STUDENTS.
