Abstract

Molecular wires containing p-phenylene sulfide units were synthesized. They could be used in material sciences and in supramolecular chemistry. Wires having 2 to 6 phenyl rings were functionalized at one end by an SH or SMe group, and at the other end, by an OH, OMe or OiPr groups. Formation of Ar S bonds in the chain was achieved by Pd-or Cu-catalyzed couplings of aromatic thiols with aromatic halides. Conditions for a clean chemoselective ...
