Doping via self-assembled macromolecules might offer a solution for developing single atom electronics by precisely placing individual dopants at arbitrary location to meet the requirement for circuit design. Here we synthesize dendrimer-like polyglycerol macromolecules with each carrying one phosphorus atom

A series of gold(i), gold(iii) and cationic gold(i) complexes of tris(4-methoxyphenyl)phosphine and tris(2,6-dimethoxyphenyl)phosphine were synthesised and fully characterised by spectroscopic methods. The molecular structures of selected complexes were also determined by X-ray diffraction analysis. The prepared complexes [AuX{P(C6H4-4-OMe)3}] [X =
