Hyperbranched polymer-cored star polyfluorenes as blue light-emitting materials

Pyrene-cored blue-light emitting [4]helicenes: synthesis, crystal structures, and photophysical properties.

The synthesis, crystal structures and photophysical properties of two types of pyrene-cored blue-light emitting [4]helicenes (7 and 9) are reported. The chemical structures of all synthesized compounds were fully confirmed by 1H and 13C NMR spectra, mass spectroscopy as well as elemental analysis. Single-crystal X-ray analysis of these [4]helicenes revealed that there are two types of laterally...

Polyfluorenes as Materials for Photolumnescence and Electrolumnescence

Aggregation-enhanced emission active tetraphenylbenzene-cored efficient blue light emitter.

A tetraphenylbenzene (TPB) cored luminophore of TPB-AC with aggregation-enhanced emission characteristics was designed and synthesized. TPB-AC could be potentially applied for the fabrication of high performance organic light-emitting diodes (OLEDs) with blue light emission.

Polymer nanofibers as novel light-emitting sources and lasing material

Polymer microand nano-fibers, made of organic light-emitting materials with optical gain, show interesting lasing properties. Fibers with diameters from few tens of nm to few microns can be fabricated by electrospinning, a method based on electrostatic fields applied to a polymer solution. The morphology and emission properties of these fibers, composed of optically inert polymers embedding las...
