Protonated versions of N-heterocyclic carbenes (NHC,H(+)) are classically prepared by closing the ring through the introduction of the CH+ fragment. He we report a totally different synthetic approach, which can be viewed as the addition of a 1,3-diazaallyl anion to

Recently, high-energy density cells containing nickel-rich cathodes and silicon-based anodes have become a practical solution for increasing the driving range of electric vehicles. However, their long-term durability and storage performance is comparatively poor because of the unstable cathode-electrolyte-interphase (CEI) of

Films of zwitterionic polymers are increasingly explored for conferring fouling resistance to materials. Yet, the structural diversity of polyzwitterions is rather limited so far, and clear structure-property relationships are missing. Therefore, we synthesized a series of new polyzwitterions combining ammonium
