Halogen substitution reshapes overcrowded π-conjugated systems by affecting molecular twisting thus influencing their redox behaviour.
A series of quaternized poly(arylene fluorenylidene piperidinium)-based copolymers were synthesized and the effect of biphenylene groups on the thin membrane properties was investigated for the application in alkaline water electrolyzers.
The asymmetric catalytic synthesis of 1,2-diamines has received considerable interest, due to their presence in biologically active compounds and their applications for the development of synthetic building blocks, chiral ligands and organocatalysts.
Germaborene chemistry is presented: halide substitution by carbon nucleophiles, Cp*Al insertion into the B–Br bond, cycloaddition of CO2, dimethylbutadiene and selenium and coordination of CuBr, AuCl and Fe(CO)4 fragments at the B
Ge double bond.
A polycatenated HOF has been constructed from supramolecular embraced pairs of macrocyclic modules, featuring fluorescent detection of nitrobenzene in water.
