Obiettivi formativi

The course provides an overview on preparation and typology of functional materials exploitable in photonics and organic-based semiconductors and an overview on photophysical and photochemical aspects involved in organic reactions stimulated by electromagnetic radiation. Basic retrosynthesis concepts used in organic synthesis strategies will be also provided.
O1 – Knowledge and understanding
The course will provide an overview
- on the synthesis of organic materials with important optical and electronic properties and application in photonic and electronic fields (i.e organic-based semiconductors, polymers for ectroluminescent systems, organic conductors and organic PV cells.
-of the basic concepts of organic retrosynthesis and the aspects and concepts related to organic photochemistry.
The course aims at providing the student of the knowledge and understanding suitable to :
1) recognize the unsaturated and conjugated organic systems with potential II and III order non-linear optical responses
2) individuate structural parameter important for observing II and III order non-linear optical responses in organic molecular and polymeric systems.
3) carry out a reasonable retrosynthetic analysis on the selected structures to select possible and efficient synthetic strategies.
4) mastery adequately the reactivity of the principal organic functionalities and its application to the synthesis of unsaturated conjugated organic systems; mastery in transition metal catalyzed cross-coupling reaction.
5) manage the synthesis of the main polymeric and oligomeric materials with potential application as conductors, semiconductors and luminescent materials.
6) describe the principal photophysical and photochemical processes involved in the interaction between matter and electromagnetic radiation.
The student is required to possess an adequate knowledge, understanding and mastery of organic chemistry
02 – Applying knowledge and understanding
During the assessment method, the student should demonstrate an adequate capability in understanding the concepts provided and in applying them:
1) to individuate the important structural and electronic parameters to observe non-linear optical behavior and in “Push-Pull” structures.
2) To apply the retrosynthetic concepts in simplifying the synthetic strategy for organic systems with non-linear responses individuating the suitable bond disconnections, the corresponding generated synthons by disconnection and the suitable synthetic equivalents.
3) to have an adequate managing of the reactivity of main functional groups.
4) to couple unsaturated units catalysed by transition metals.
5) to the synthesis of oligomeric and polymeric organic materials.
6) to the mastery of photophysical and photochemical processes induced by interaction of electromagnetic radiation with matter.
O3 – making judgements
The course will allow the student autonomously:
1) to recognise the more useful structural parameters for observing II and III order non linear phenomena and electronic and optical properties exploitable in conducting, semiconducting, PVc and electroluminescent organic-based devices.
2) to propose a reasonable synthetic strategy based on a ratiocinated retrosynthetic approach.
3) to use synthetic protocols based on classical organic chemistry strategies or by resorting to transition metal catalysed protocols.
4) to understand the basic concepts at the base of UV-Vis electromagnetic radiation with the organic matter
O4 – Learning skills
By applying the competences provided by this course, the student will be able:
1) to understand the optical and electronic properties of conjugated unsaturated organic systems.
2) to understand the strategies used in the preparation of organic semiconducting, luminescent photovoltaic both molecular and polymeric devices.
3) to understand the processes involved in the interaction of electromagnetic radiation with organic based materials.
