Note: SOM stands for Spiro-OMeTAD. Li salt for Bis(trifluoromethylsulfonyl)amine lithium salt, 99.95% trace metals basis. TBP for 4-tert-Butylpyridine. CB for Chlorobenzene. DCM-pyran for 4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran. Solutions were spin coated on SQ-1 acceptor dye-sensitized TiO2 nanotubes at 2000 rpm. The 0.02 M TiCl4-treated TiO2 nanotubes are from 500 to 600 nm in length, and 20 to 28 nm pore size.
