Dispersion stability of Au nanoparticles in toluene encapsulated by tetraarylthiol 3 and crosslinked with G-1 catalyst at variable loadings, followed by exposure to 40 mM C12SH. Dispersions were maintained at ambient temperatures except at point a (70 °C, t=67–69 h) and point b (70 °C, t=142–158 h). The thermal stability of nanoparticles encapsulated by uncrosslinked 3 in the absence of competing surfactant (grey circles) was also evaluated.
