Low efficiencies of soluble blue emitter materials remain a major issue in the development of printed organic light-emitting devices. n-Alkylated carbazoles or sterically demanding ortho-substituted diphenylamines were employed as donor elements to increa

Selective bis-sulfenylation reactions of aryl dihalides have been achieved by copper-catalyzed C-S coupling reactions under mild conditions of refluxing EtOH (80 °C). Employment of disulfides as thiolating reagents enables the production of various bis(phenylthio)benzenes with excellent selectivity, and no products from mono C-S coupling are isolated. the Partner Organisations 2014.
p-Phenylene sulfide oligomers and their properties. Ar-S couplings mediated by copper or by fluorine substitutions

A series of monodisperse p-phenylene sulfide oligomers were efficiently synthesized by using a bidirectional growth. A strategy combining Cu-catalyzed Ar-S couplings for small oligomers and fluorine aromatic substitutions by aryl thiolates for longer ones was put forward. The latter method is superior to Cu-catalyzed reactions for longer oligomers. Fluorine chemistry brings some new advantages such as solubility and reactivity. Qualitative crystallinity studies were reported according to the oligomer size and the functional series, by using a microscope equipped with a heating stage and a camera.
