2 propanol

Polystyrene pellets (Styron
634-71) were purchased from Resinex. As provided by the supplier,
the mass average molar mass, M_w, is 265 000
g·mol^–1, and the dispersity of the molar mass
distribution, Đ, is 2.65. Five solvents were
chosen to study the influence of the solvent type on the rheology
of the polymer solutions. The choice of the solvents was based on
their properties, such as molecular structure, melting and boiling
point, viscosity, and toxicity. These solvents include n-butyl acetate (99% purity, Alfa Aesar), o-xylene
(99% purity, Alfa Aesar), tetrahydrofuran (99% purity, Sigma-Aldrich,
Merck), anisole (99% purity, Sigma-Aldrich, Merck), cyclohexanol (99%
purity, Chem-Lab), and 2-propanol (99.8% purity, Chem-Lab). Two “green”
solvents, (R)-(+)-limonene (93% purity, Sigma-Aldrich,
Merck) and geranyl acetate (90% purity, Sigma-Aldrich, Merck) are
included as well. The solvents were used as-received, without any
purification.

Cadmium oxide (≥99.99%), sodium myristate (Na(myr), ≥99%), octanoic acid (≥98.0%), 1,2,3,4-tetrahydronaphthalene (tetralin, synthesis grade) and chloroform-d (CDCl₃, d, 99.8%) were purchased from Merck/Sigma-Aldrich. n-Hexadecane (HD, 95%) was purchased from Fiers. 1-Octadecene (ODE, 90%), oleic acid (OA, 90%) were purchased by Alfa Aesar. Cadmium nitrate tetrahydrate (99+%), propionic acid (99.5+%), toluene (>99%), methanol (99.8+%) and 2-propanol (IPA, 99+%) were purchased from Chem Lab. Acetonitrile (ACN, 99.9%) was purchased from Carl-Roth. Selenium powder (≥99.99%) and cadmium acetate dihydrate 98% were purchased by Acros Organics. All chemicals were used without further purification. A vacuum/dry nitrogen gas Schlenk line was used for nanocrystal syntheses. The purifications were conducted in air unless specified otherwise.
