An alignable fluorene thienothiophene copolymer with deep-blue electroluminescent emission at 410 nm

Abstract
An alignable, liquid-crystalline fluorene fused-ring thienothiophene copolymer has been synthesized with electroluminescence peaking at 410 nm for deep blue, polarised emission in polymer light-emitting diodes, light-emitting transistors and photonic structures.
