Graft copolymerization reactions of polyfluorene-based macroinitiators with vinylidene fluoride (VDF) were challenged to achieve multi-functional materials. In the first place, a reactive fluorene monomer was prepared by the incorporation of end-functionalised alkyl moieties, which was then converted to statistical polyfluorenes with ordinary dioctyl fluorene and colour-modulating comonomers. The resulting polyfluorenes with hydroxyl groups were transformed to macroinitiators working in a RAFT polymerization condition, and finally graft copolymerization reactions with VDF were carried out successfully. Red, green and blue copolymers were analysed by thermal and spectroscopic means to look at their unique structural features. When the copolymers were introduced into devices as an active layer, they showed light-emitting, ferroelectric and piezoelectric properties, demonstrating their potential use as synchronized piezoelectric-luminescent (SPL) materials. |
