Supramolecular conducting materials

Lead Research Organisation: University of Bristol
Department Name: Chemistry

Abstract

The preparation of novel functional polymers is an active research field. The introduction of
supramolecular polymerisations, and recently, controlled supramolecular polymerisations,
has ensured that a whole range of new systems are explored.
In this project several new routes to the formation of conducting supramolecular polymers
will be explored, based on the assembly and use of a corannulene core structure. This
approach will provide a number of advantages: 1) control over the supramolecular
polymerisation (based on the work of Aida), 2) addition of functionality through the
attachment of electroactive aniline-based side-arms, and 3) switchable and self-healable
properties.

Description Key findings:
-A novel method to control both length and width of nanoscale fibres (supramolecular polymers) based on the functional perylene diimide unit has been developed.
-A strategy to control the nanoscale morphology, mechanisms of formation, and function (light absorbance, fluorescence and electrical conductivity) of similar supramolecular polymers has been developed by rational substitution of core oxygen atoms for sulphur.

Negative results:
-An end-capping approach to controlling the length and structres of similar nanoscale fibres was attempted but was unsuccessful.
Exploitation Route -Methods of controlling supramolecular polymers worked on during this project are being further explored for application in organic solar cells.
-The oxygen to sulphur substitution strategy is being further investigated by another research group member with the aim of forming more complex and hierarchical nanoscale structures.
