chloride (97%), bis(trimethylsilyl)sulfide (a.k.a.,
hexamethyldisilathiane, synthesis grade), oleylamine (70%, technical
grade), oleic acid (90%, technical grade), 1-ODE (90%, technical grade),
cyclohexane (≥99%, ACS reagent grade), hexane (95%, anhydrous),
methanol (99.8% anhydrous), thiophene (≥99%), and n-decane (≥99%, synthesis grade) were purchased from Sigma-Aldrich.
Acetone (99.8%, extra dry) and 1,2,3,4-tetrahydronaphthalene (a.k.a.
tetralin, TCI America, ≥ 97%) were purchased from VWR. All
chemicals were used without further purification with the exception
of oleylamine and 1-ODE, which were each separately degassed for 1
h by cycling between nitrogen flow and vacuum on a Schlenk line at
80 °C prior to use.
