vacuum. 40 mL of pentane were then added to the colloidal
suspension, which was cooled down to −30 °C to precipitate
the particles. After filtration under argon with a cannula, the
black solid powder was washed twice with pentane (2 × 40 mL)
and filtered again before drying under vacuum. Yield: 88 mg.

Pt/PPP. 300 mg (0.9 mmol) of the [Pt(CH3)2(COD)] complex
were introduced into a Fisher-Porter reactor and dissolved with
80 mL of THF previously degassed by three freeze–pump
cycles. The resulting solution was cooled at −60 °C and a PPP/
THF solution (43 μL (0.22 mmol) per 100 mL) was added to
the reactor. The reactor was pressurized with 3 bar of H2 and
the solution was heated at 70 °C for 30 min and then stirred at
room temperature for 18 h. After this period of time, the
excess of H2 was eliminated and the volume of solvent was
reduced to 10 mL under vacuum. 40 mL of pentane were then
added to the colloidal suspension which was cooled down to
−30 °C to precipitate the particles. After filtration under argon
