Journal ArticleDOI
Designing pi-conjugated polymers for organic electronics
TL;DR: In this paper, a review of conjugated polymers with 1D and 2D topological structures is presented, and a design approach for the alternating donor-acceptor (D-A) copolymers is proposed.

Synthesis and properties of monodisperse oligofluorene-functionalized truxenes : highly fluorescent star-shaped architectures
Alexander L. Kanibolotsky,Rory Berridge,Peter J. Skabara,Igor F. Perepichka,Donal D. C. Bradley,Mattijs Koeberg +5 more
TL;DR: Spectroelectrochemical experiments reveal that compounds T1-T4 are stable electrochromic systems which change their color reversibly from colorless in the neutral state to colored (from red to purple color; approximately 500-600 nm) in the oxidized state.
Journal ArticleDOI
Polyfluorene-based semiconductors combined with various periodic table elements for organic electronics
TL;DR: In this paper, a soccer-team-like framework was proposed to illustrate the structure-property relationships at three levels: chain structures, thin films and devices, and the modelling of hydrocarbon polyfluorenes (CPFs) was summarized within the framework of a four-element design principle, in which they highlighted polymorphic poly(9,9-dialkylfluorene)s with unique supramolecular interactions, various hydrocarbon-based monomers with different electronic structures, functional bulky groups with steric hindrance effects and ladder-type, kinked

Synthesis and properties of random and alternating fluorene/carbazole copolymers for use in blue light-emitting devices
TL;DR: In this paper, random and alternating fluorene/carbazole (F/Cz) copolymers with various carbazole contents (20−50 mol %) have been designed and synthesized for use as the hole-transporting as well as light-emitting layer in blue light emitting diodes (LEDs).
Journal ArticleDOI
Poly(2,7-dibenzosilole): A Blue Light Emitting Polymer
TL;DR: Suzuki copolymerization of dibromo and bis(boronate) monomers afforded poly(9,9-dihexyl-2,7-dibenzosilole) which showed better efficiency than the corresponding polyfluorene in a single layer light emitting device.

Semiconducting Polyfluorenes—Towards Reliable Structure–Property Relationships
Ullrich Scherf,Emil List +1 more
TL;DR: In this paper, the authors focus on reliable structure-property relationships regarding substitution pattern, solid state morphology, and optical/electronic properties, and the key role of degradation-induced keto defect sites in fluorerse-type polymers and strategies for obtaining defect-free polyfluorenes.
