Abstract
A method of fractionating a semiconducting polymer wherein the semiconducting polymer comprises polymer chains comprising a defect group, the method comprising the steps of reacting the polymer chains comprising a defect group to form polymer chains comprising separating groups; and separating the polymer chains comprising the separating groups from the semiconducting polymer. The separating group may be a binding group X capable of binding to a solid substrate material 305, for example particulate silica.
Claims16
A method of treating a semiconducting polymer, wherein the semiconducting polymer comprises polymer chains comprising a defect group and polymer chains which are substantially free of defect groups;
- the method comprising the steps of:
- reacting the polymer chains comprising a defect group to form polymer chains comprising separating groups;
- and
- separating the polymer chains comprising the separating groups from the semiconducting polymer;
- wherein the semiconducting polymer is in a dissolved form.
