“…The absorption curves are reported in Figure S1 (Supporting Information) and the solubility results are reported in Table 1 . Chloroform ( CF ) is the best solvent for DPP(TBFu) 2 , which can dissolve up to 15.3 mg/mL followed by tetrabromoethane (8.25 mg/mL), thiophene ( Th ) and trichloroethylene, TCE , (7.21 mg/mL), and carbon disulfi de ( CS 2 ), tetrahydrofuran, and o -dichlorobenzene ( ∼ 4.40 mg/mL). For PC 71 BM , tetrabromoethane is the best solvent, which can dissolve over 480 mg/mL, followed by methylene iodide (357 mg/mL), o-dichlorobenzene ( ∼ 203 mg/mL), trichloroethylene (160 mg/mL), carbon disulfi de (142 mg/mL), and o -xylene, chloroform, and chlorobenzene ( ∼ 61 mg/mL).…”
