synthesized from styrenes by combining a cross metathesis and a Ru-catalyzed alkene oxidation to an assisted tandem catalytic sequence. The synthesis relies on the use of just one metathesis precatalyst, which was in situ converted to the oxidation catalyst by addition of an alkyl hydroperoxide as a chemical trigger and oxidant. The one-flask sequence can be extended beyond 1,2-diketones to quinoxalines, by

Facile ways towards the development of linear and brush-type zwitterionic conjugated polyelectrolytes possessing hole or electron blocking abilities are presented using combination of polymerization techniques, such as Suzuki or Stille cross coupling, Grignard Metathesis Polymerization and Atom transfer radical polymerization. These zwitterionic conjugated polyelectrolytes will serve as excellent interface materials in various optoelectronic devices.
