Staff Profile

Prof. W. James Feast, CBE, FRS

Emeritus Professor in the Department of Chemistry

(email at w.j.feast@durham.ac.uk)

Research Interests

Professor Feast reached formal retirement age in 2003 and now works chiefly from home as an Emeritus Professor. He no longer runs a group and he does not recruit graduate students or post doctoral co- workers. 

His interests are concerned with functional organic materials: design, synthesis, characterization and properties, including:

  • Materials with novel electrical, magnetic and optical properties;
  • Fluoropolymers;
  • Novel topologies, dendrimers and hyperbranched polymers;
  • Self ordering systems;
  • Biomaterials.

Control of size, stereochemistry and organization in established and novel polymers leads to control of properties and function.  Professor Feast's group made contributions to this theme including:

  • synthesis of stereoblock copolymers via ligand exchange at the active chain end of a living ROMP system;
  • demonstration that the mechanical properties of blends of dendritic and linear polymers are very sensitive functions of the size of the dendrimer;
  • synthesis of self-ordering polyene and oligothiophene systems displaying enhanced charge carrier mobilities;
  • demonstration that solid state photoluminescence efficiency is a sensitive function of cis/trans ratio in poly(arylene vinylene)s;
  • control of branching ratio in an AB2 addition polymerisation, leading to dendritic solution behaviour.
  • Synthesis of chiral self assembling sexithiophenes
  • Insights into the long term stability of electroactive materials and the importance of high purities.
