Oligomeric Compatibilizers for Control of phase Separation in Conjugated Polymer Blend Films

Blending conjugated polymers without phase separation for fluorescent colour tuning of polymeric materials through FRET

The fluorescence properties of conjugated polymer blends were investigated using a combination of excitation energy donor and acceptor conjugated polymers encapsulated by identical cyclic sidechains. Wearing this 'uniform', the polymers did not phase-separate in the blends. As such, these polymers provide an effective ensemble for designing fluorescent polymeric materials.

Fluorene-based macromolecular nanostructures and nanomaterials for organic (opto)electronics

Nanotechnology not only opens up the realm of nanoelectronics and nanophotonics, but also upgrades organic thin-film electronics and optoelectronics. In this review, we introduce polymer semiconductors and plastic electronics briefly, followed by various top-down and bottom-up nano approaches to organic electronics. Subsequently, we highlight the progress in polyfluorene-based nanoparticles and nanowires (nanofibres), their tunable optoelectronic properties as well as their applications in polymer light-emitting devices, solar cells, field-effect transistors, photodetectors, lasers, optical waveguides and others. Finally, an outlook is given with regard to four-element complex devices via organic nanotechnology and molecular manufacturing that will spread to areas such as organic mechatronics in the framework of robotic-directed science and technology.
