Module aims

This module builds on the knowledge established in Year 1 of the Chemistry programme. It introduces students to the way in which modern materials have changed our lifestyle beyond recognition, providing an insight into the cutting edge of materials chemistry and how it underpins the technological developments expected in the 21st century. The module focuses in particular on how the molecular structure controls the materials properties and connects with real practical applications. The module introduces general aspects in the topic of materials science (structure and physical properties) and then goes on to explore specific applications of modern organic materials such as LCD technology, widely used in televisions and mobile phones, and supramolecular organisation in polymers. These concepts are followed by studying how nanotechnology is increasingly being integrated into modern advanced materials. In particular, the course will illustrate how developing materials with well-defined molecular nanostructures can lead to new types of behaviour and high-tech applications – for example in optical electronics, imaging and nanomedicine.

Module learning outcomes

Subject content:

  • to examine how the structures of molecules can affect the physical properties of a material, in particular the relationship between molecular structure and mechanical, magnetic and electrical properties.
  • to see how the optical and dielectric properties of liquid crystals and liquid crystal polymers are used in modern TVs and computer screens.
  • to understand the importance of the chemical approach to nanomaterials
  • to study the preparation, analysis and applications of metal nanoparticles.
  • to develop an understanding of conjugated polymers and their applications in opto-electronic and electro-optic devices.
  • to understand how polymer composition and architecture at the nanoscale imparts unique properties and behaviour by examining dendrimers, hydrogels and block copolymers.
  • to study organic-inorganic hybrid materials and to examine how the incorporation of metals leads to new properties and applications.

Academic and graduate skills:

  • Students will be able to explain the link between materials properties and the molecular structure.
  • Students will gain an insight into how fundamental chemistry plays a vital role in informing the assembly of nanomaterials and how synthetic chemists are an essential part of the ‘nano-revolution’

Module content

Nanotechnology relies heavily on our ability to control molecular assembly on the nanometre scale. This module concentrates on the chemical approach to materials and will focus on the study of a range of molecular and nanoscale building blocks with strictly controlled size, shape, composition and surface structure, the concepts and methods used in their synthesis and their properties. A further aim is to be able to link their molecular structure with their bulk properties and to learn how to manipulate them at molecular level in order to attain the properties needed for specific applications. The module will cover the study of liquid crystalline materials, metal nanoparticles, including their synthesis and techniques for their characterisation, “designer” polymers with specific composition and architectures, the role of metals in polymeric materials and how the assembly of nanoscale building blocks leads to structural colour.

Module feedback

Students will receive feedback on their performance in their assessed workshop within 4 weeks. Oral feedback for the formative workshops will be given during the sessions.

Closed exam results with per-question breakdown are returned to the students via supervisors within 5 weeks (as per special approval by the University Teaching Committee). Outline answers are made available via the Chemistry web page when the students receive their marks, so that they can assess their own detailed progress/achievement. the examiners' reports for each question are made available to the students via the Chemistry web pages. 

Indicative reading

To be provided by individual tutors: this is a research-led course so up-to-date scientific publications will form the majority of the reading.



The information on this page is indicative of the module that is currently on offer. The University is constantly exploring ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary by the University. Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.
