98678 - MOLECULAR NANOTECHNOLOGY

Learning outcomes

At the end of the course the student has acquired the basic concepts and the main strategies for the bottom-up construction of functional nanostructures, starting from molecules and using the paradigms of supramolecular chemistry: molecular devices and machines, dendrimers, nanoparticles, self-assembled monolayers and thin films.

Course contents

Prerequisites: knowledge of the fundamental concepts of spectroscopy, photochemistry and electrochemistry.

Attendance: the course has no compulsory attendance, but attending lessons is highly recommended.

Artificial molecular machines: recent achievements and potential applications

Readings/Bibliography

The course covers advanced topics of great scientific relevance and therefore in continuous evolution. There is no textbook covering the whole program; the following texts are recommended for the study and in-depth study of parts of the course:

1) J.-M. Lehn, Supramolecular Chemistry – Concepts and Perspectives, VCH, Weinheim, 1995 (part 1, 2, 4 of the programme).

2) V. Balzani, A. Credi, M. Venturi, Molecular Devices and Machines – Concepts and Perspectives for the Nanoworld, Wiley-VCH, Weinheim, 2008 (parti 1, 3, 7).

3) D. S. Goodsell, Bionanotechnology: Lessons from Nature, Wiley, New York, 2004 (part 1 and 7).

4) C. N. R. Rao, A. Muller, A. K. Cheetham (Eds.), The Chemistry of Nanomaterials, Vol. 1 e 2, Wiley-VCH, Weinheim, 2004 (part 1 and 6).

Other relevant recommended references will be reported on the slides of the presentations used in class.

Teaching methods

The module is carried out in the second semester, and consists of class lectures that illustrate the basic principles of supramolecular chemistry and nanosciences; for each specific topic, the introductory concepts as well as some singificant examples taken from the scientific literature are presented.

Assessment methods

The learning assessment takes place only with the final exam. The acquisition of the learning outcomes is ascertained by means of an oral exam with an average duration of 30 minutes. The exam consists of two questions on the themes dealt with in the course.

The assessment will be determined by the following factors: clarity of presentation, language accuracy, conciseness, and thoroughness of the information provided.

Students with learning disorders and\or temporary or permanent disabilities: please, contact the office responsible (https://site.unibo.it/studenti-con-disabilita-e-dsa/en/for-students ) as soon as possible so that they can propose acceptable adjustments. The request for adaptation must be submitted in advance (15 days before the exam date) to the lecturer, who will assess the appropriateness of the adjustments, taking into account the teaching objectives.

Teaching tools

Overhead projector, PC, video projector, powerpoint presentations, videos.
