Summary of the subject: According to its logical construction, the course can be divided into three parts. The first part describes the principles of supramolecular objects of various chemical nature with physical analysis of supramolecular interactions. The "philosophy" of the supramolecular device is covered separately. Based on this, the second part sets out the basic principles and conceptual approaches to the formation of supramolecular ensembles of various architectures: multilayer inorganic / organic nanohybridized clathrates, semiconductor / cavitation hierarchical structures and their intercalates. In the latter perspective, considerable attention is paid to the first identified effects of selective cation - anionic recognition by hierarchical inorganic / cavitation ensembles. After elucidating the basic physical properties of supramolecular ensembles, their behavior in the electric, magnetic, and light wave fields is then consistently elucidated. The third part systematizes and summarizes the latest trends in the theory of supramolecular systems. In particular, the latest effects such as interference blockade of Faraday current formation, quantum reactance of supramolecular hierarchical objects, the appearance of rotating polaron and the mechanisms of operation of devices based on resonant tunneling and other quantum mechanical effects are analyzed for the first time. Theoretical models for quantum-dimensional N-barrier structures and nanogenerators of electric energy are organically intertwined in this information.

Критерії оцінювання результатів навчання: The procedure and criteria for assigning points and grades:
Theoretical questions are intended to test students' skills in understanding theoretical material. The answer should be as complete and reasoned as possible.
- The maximum number of points (mcp) for a question is given to a student who has fully covered the question;
- 70-90 % of MCQs - the question is generally covered, but there are minor inaccuracies or other shortcomings;
- 50-70% of the MCB - the answer to the question is not given in full and / or there are significant errors;
- 30-50% of the MCQs - an attempt is made to answer the question, but gross mistakes are made and/or the question is not covered in general. The student will deserve the same mark if he/she draws incorrect conclusions based on logical assumptions that contain correct reasoning;
- 10-30% of the marks - an unsuccessful attempt is made to answer the question, only some of the reasoning and/or formulas are correct;
- 0 points - none of the written formulas is relevant to the question, all the reasoning is wrong or completely absent.
The tasks are intended to test students' skills in practical solving of physical problems. Problems should be solved with as much explanation as possible and, if necessary, with a figure.
- the maximum number of points (mcp) is given to a student who has completely solved the problem;
- 70-90% of the maximum marks are awarded for a solved problem with minor inaccuracies;
- 50-70% of the MCB - an error(s) was made in the solution that affected the result, but the approach to the solution was correct;
- 30-50 % of MCB - an attempt was made to solve the problem, but gross errors were made and the result is incorrect;
- 10-30 % of MCB - an unsuccessful attempt to solve the problem was made and one or more correct formulas related to the problem were written;
- 0 points - none of the written formulas is relevant to this problem, or the student did not even attempt to solve the proposed problem.
