摘要：
Upon reacting with tetrakis(hydroxymethyl) phosphonium chloride, 15 nm citrate gold nanoparticles rapidly assemble into linear chains, followed by slowly disassembling into monodisperse components. This work highlights the first example of P-31 NMR on gold particles of this size and suggests that the phosphonium is oxidized on-particle, contributing to particle disassembly.
