A new ligand–metal combination (see picture, Ni green, Br brown, N blue, O red, C gray) was designed to be cationic and to benefit from removal of electron density by the action of a Lewis acid on the ligand framework. In the presence of various activators, the resulting catalytic site is highly active for ethylene polymerization and capable of polymerizing α‐olefins to high molecular weights.

In recent years, end-functional poly(3-hexylthiophene) (P3HT) has proven to be instrumental in the continued development and innovation within the broad conjugated polymer arena, enabling a variety of applications, particularly in organic electronics. The availability of P3HT with controlled molecular weights, low polydispersity, and importantly, a wide range of reactive end-groups not only serves as a key building block for the preparation of conjugated block copolymers but also facilitates the development of hybrid nanocomposite materials via inorganic surface modification strategies. This Highlight focuses on the synthetic approaches to endfunctional P3HT and the impact of these systems in emerging technologies. V C 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Aktivierung aus der Distanz: Eine neuartige Katalysatorvorstufe, die kationisch ist und vom zusätzlichen Abzug von Elektronendichte durch Einwirkung einer Lewis‐Säure auf das Ligandengerüst profitiert (siehe Bild, Ni grün, Br braun, N blau, O rot, C grau), ist in Gegenwart einer Vielzahl an Aktivatoren hoch aktiv bei der Ethylenpolymerisation und überführt α‐Olefine in hochmolekulare Polymere.
