Synthesis of DPA dendron encapsulated gold clusters with metal-assembling function

Synthesis of DPA dendron encapsulated gold clusters with metal-assembling function

Gold clusters modified with first, second and third generation dendritic polyphenylazomethines (DPA) were synthesized by an exchanged reaction of corresponding DPA dendron thiols. Measurements by high performance perfect sizer (HPPS) and TEM reveal that their diameters increase with a change in the...
