•Single oral exam
•Evaluation of the guided readings assignments
during the exam the student will have to answer 3 general questions on the topics discussed in both standard and video lesson. Questions will focus on the capability to reorganize the concepts discussed in classes. Students will be encouraged to reason on the possibile use of their notions in practical examples/aplications.
Molecular materials are rapidly gaining momentum, both in terms of scientific research and technological applications. Aim of the course is to provide a detailed knowledge of the structure properties relationships ruling the behaviour of such materials, with particular emphasis on electronic, optical and optoelectronic properties.
Non-covalent interactions and molecular aggregates and solids: dipole-dipole, ion-dipole, hydrogen bonding, coordinative bonding and van der walls interactions. Examples of host guest interactions in solution: crown ethers, coronands, criptands, calixarenes and resorcinarenenes, rotaxanes and catenanes. Materials for nonlinearoptics: theoretical background. Molecular Materials for optoelectronics. Push-pull derivatives and BLA model. Bulk materials (poled polymers and sol-gel, Langmuir-Blodgett films, self assembled superlattices). Two-phonton absorbing materials and related applications (up converted lasing and imaging, optical limiting, 3D microfabrication) Synthesis and characterization of organic semiconductors. Transport properties in charge transfer complexes. Conducting polymers (polyacetylene, PPV, polyetherocycles). Electrochemical and oxidative polymerizations. Cross-coupling polymerizations.
Electrochromic materials and devices: background and design criteria for molecular and polymeric materials. Specific issues with devices assembly. Materials for displays and lighting: Working principle and device architecture of OLEDS. Molecular materials polymeric materials. Solid state down converting devices. Luminescent solar concentrators. Organic rechargeable batteries. Elements of organic materials for bioimaging and photodynamic therapy.
The course is blended and organized in class activities, videolessons and guided reading activites
Class lessons covers the following arguments
•Elements of conjugated materials design (building blocks)
•Elements of supramolecular chemistry (non covalent interactions)
•Conjugated molecules and materials having Nonlinear Optical Behavior
•Photoresists
•Organic polymeric semiconductors and conductors
•Electrochromic materials
•Organic Field Effect Transistors
•Soft lithography techniques
Video lessons are dedicated to :
•Scientific literature and databases
•Luminescent solar collectors
•Photodynamic therapy
•Organic bulk heterojunction solar cells
•Charge transfer complexes
•Organic light emitting devices
•DNA origami
Students are inveted to take part to guided readings activites thus organized:
Homework – guided reading (on platform in groups)
•You will have to provide a referee report for a scientific paper that you assume is not in the final published form but rather at the submitted to the referees step.
•During classes you will have to repeat this exercise for 7 different papers
•Reports are to be posted directly on the course platform using the appropriate section (consegna compito)
•Activities are moderated through a forum. Active discussions amongst fellow student on platform are encouraged.
