We have developed a synthetic approach that allows us to synthesise monodisperse organic
semiconductor macromolecules on the gram scale. In contrast to conjugated polymers, batches
are prepared with 100% reproducibility and the products can be isolated in high purity. These
attributes are extremely well valued, because subsequent work towards device optimisation
(design, processing, annealing, etc.) can rely on the consistent behaviour of the organic
semiconductor. Such compounds have been made for photonic and optoelectronic applications,
such as organic lasers, downconvertors in hybrid LEDs, visible light communications, OLEDs
and OPVs.
For the applications mentioned above, the materials have been designed to be amorphous with
excellent film-forming properties and compatibility in composites. The latter includes hybrid
LED devices and as wide band gap materials in optically transparent OPVs. This talk will
highlight some of our recent work on the synthesis and application of star-shaped organic
semiconductors [1-4].
