文摘
Ferrocene (Fc) in ether reduces HAuCl<sub>4sub> in water within seconds under ambient conditions in air upon stirring, forming ferricinium chloride stabilized water-soluble 20 nm gold nanoparticles (AuNPs) that are redispersible in the presence of poly(N-vinylmethylpyrrolidone) or NaBH<sub>4sub> + thiol. After reduction with NaBH<sub>4sub> yielding Fc and 26 nm sodium poly(hydroxyborate) stabilized AuNPs, the core size no longer changes following reactions with thiols providing (RS)<sub>nsub>AuNPs.
