IGNOU MCHE-013
Supramolecular Chemistry · 2026–27 Session
MCHE-013 introduces
students to the fascinating field of Supramolecular Chemistry, which
focuses on chemical systems formed through non-covalent interactions between
molecules. The course explores molecular recognition, host–guest chemistry,
self-assembly, supramolecular structures, and the applications of these systems
in areas such as catalysis, sensing, medicine, and nanotechnology.
The course helps students understand how weak intermolecular forces can control the structure, properties, and functions of complex molecular systems.
