Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

• Explain non-covalent interactions, molecular recognition and self-assembly and how these can be exploited to prepare functional molecules and materials for a wide-range of applications.
• Discuss the role of supramolecular chemistry in organic chemistry, chemical biology, materials science and nanotechnology.
• Have an appreciation of the significance and application of supramolecular chemistry, including in dynamic combinatorial chemistry, materials chemistry (e.g. soft materials, porous hybrid and other framework solids), biological systems and the controlled construction of nanoscale entities.

The syllabus, which is described in outline below, is aligned with the following QAA benchmark statements for chemistry at FHEQ Level 7 (Masters).

• to extend students' comprehension of key chemical concepts and so provide them with an in-depth understanding of specialised areas of chemistry;
• to develop in students the ability to adapt and apply methodology to the solution of unfamiliar types of problems;
• to instill a critical awareness of advances at the forefront of the chemical science discipline;
• to prepare students effectively for professional employment or doctoral studies in the chemical sciences;
• the ability to adapt and apply methodology to the solution of unfamiliar problems;
• knowledge base extends to a systematic understanding and critical awareness of topics which are informed by the forefront of the discipline;
• problems of an unfamiliar nature are tackled with appropriate methodology and taking into account the possible absence of complete data. This unit is a research led course with many examples coming from the recent scientific literature.

Topics to be covered in this module include:

Principles of Molecular Recognition and Self-Assembly

Overview of intermolecular forces in the context of the structural and thermodynamic origin of molecular recognition processes and the techniques use to study and measure non-covalent interactions. Historical development of supramolecular chemistry.

Applications of Self-Assembly in Host-Guest Chemistry and Catalysis

The principles and applications of supramolecular chemistry including: hosts for anions, cations and neutral molecular species; supramolecular catalysis through hydrogen bonding, preconcentration, self-assembly of catalysts and preorganisation of catalyst-substrate systems

Supramolecular aspects of chemical biology

The supramolecular chemistry of natural systems (DNA, peptides) and their chemical modification to introduce further functionalities; principles and applications of nano-biotechnology.

Self-assembly of complex structures

Extension of supramolecular principles and dynamic covalent chemistry to larger architectures including gels, cages, interlocked molecules, molecular machines, and self-replicating and evolving systems.

Metal and Covalent Framework Materials

Synthesis, properties and applications of modular porous solids such as covalent-organic frameworks (COFs) and metal-organic frameworks (MOFs), including supramolecular templating of hierarchically porous solids. Applications to be covered may include: storage and separation of strategically important gases (H2, CO2, CH4), drug delivery, catalysis and energy. For each application the challenges will be discussed and an evaluation of how these can be addressed by the composition and design of the materials presented. The dynamic behaviour of frameworks will also be discussed with respect to the (supramolecular and/or coordination) interactions which sustain the extended network structures.
