Block copolymers from ionic liquids for the preparation of thin carbonaceous shells
Autor: Sadaf Hanif, Bernd Oschmann, Dmitri Spetter, Muhammad Nawaz Tahir, Wolfgang Tremel, Rudolf Zentel
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 13, Iss 1, Pp 1693-1701 (2017)
This paper describes the controlled radical polymerization of an ionic-liquid monomer by RAFT polymerization. This allows the control over the molecular weight of ionic liquid blocks in the range of 8000 and 22000 and of the block-copolymer synthesis

Publikováno v: Angewandte Chemie. 129:15314-15318
We demonstrate a novel crosslinked disulfide system as a cathode material for Li-S cells that is designed with the two criteria of having only a single point of S−S scission and maximizing the ratio of S−S to the electrochemically inactive framew

Publikováno v: Chemical Communications. 53:1888-1891
We report a metal-free strategy for the chain-end modification of RAFT polymers utilizing visible light. By turning the light source on or off, the reaction pathway in one pot can be switched between either complete desulfurization (hydrogen chain-en

Publikováno v: Journal of Colloid and Interface Science. 478:155-163
In our present work we developed a novel graphene wrapping approach of Ni@Fe2O3 superparticles, which can be extended as a concept approach for other nanomaterials as well. It uses sulfonated reduced graphene oxide, but avoids thermal treatments and
