TL;DR: Density function theory (DFT) calculations showed that these iridium complexes had a wide band gap, owing to the introduction of the strong electron withdrawing perfluoro carbonyl group, and time-dependent DFT calculations suggested that their lowest triplet excited state was dominated by a HOMO → LUMO transition.

TL;DR: In this paper, four new quaterthiophene derivatives with end-groups composed of dicyclohexyl ethyl (DCE4T), dicyclehexyl butyl (DCB4T) and cyclohexylon butyl(CB4T).

TL;DR: The thermal annealing effect on the mobility enhancement, the crack development, and the stability of 6,13-bis(triisopropylsilylethynyl) (TIPS)-pentacene field effect transistors (FETs) with a solution-processed polymeric insulator was investigated in this article.

TL;DR: Poly(5′,5′-bithiophene-alt-2,6-[(1,5-didecyloxy)naphthalene]) (PBDN) as mentioned in this paper was synthesized from 2,6-dibromo-l,5Didecyloxynaphthalenes and 1,1′-[2,2′-Bithiopane]-5,5''-diylbis[1,1, 1-trimethylstannane] and was used as the active layer in organic thin-film transistors (

TL;DR: In this article, the synthesis and device characterization of a novel iridium complex using a phenylpyridine derivative containing an imide functional group as a bis-cyclometallized ligand ((impy)2Ir(acac)) for organic light-emitting diodes was reported.
