Chronoamperometric measurements were carried out on an EC-Lab SP-200 (Bio-Logic Science Instruments SAS) in a three-electrode-cell system with a FTO coated glass slide as the working electrode, Ag/AgCl2 electrode (-0.35 V vs standard hydrogen electrode) as the reference electrode, platinum wire as the counter electrode. The photocatalyst was dispersed in acetone (1 mg mL -1 ) and 100 µL were added to 100 µL of Nafion 117 (5 wt. % in a mixture of lower aliphatic alcohols and water). This mixture (30 µL) was drop-casted onto an FTO glass working electrode. The sample was then dried under in a fume hood overnight at room temperature. A three-electrode-cell system containing an aqueous sodium sulfate solution (0.01 M) was purged with N2 for 10 minutes. The measurement was performed by illuminating the front of the working electrode with a solar simulator (1 Sun, Oriel Instruments LSH-7320 (IEC ABA certified). 118. The X-ray crystal structure was refined as a two-component twin with a HKLF 5 file format and BASF refined to 0.106. X-ray data was detwinned using the TwinRotMat function Platon. Figure . ). In the crystal structure, there are large 1-D voids that contain disordered electron density that could not be accurately modelled. It was therefore necessary to use the SQUEEZE routine in Platon during the final refinement cycles. SQUEEZE located two 649 Å 3 voids which each had a disordered electron count of 289 e-. As a result, 6 DMF and 6 CHCl3 solvent molecules were tentatively added to the unit cell atom count. Disordered electron density that could be located was modelled as severely disordered CHCl3. The disordered CHCl3 molecules were refined with bond distance restraints (DFIX, DANG and SADI in SHELX). [a] Fluorescence life-times were obtained from fitting time-correlated single photon counting decays to a sum of three exponentials, which yield τ1, τ2, and τ3 according to ∑ (𝐴 + 𝐵 𝑖 exp (-𝑡/𝜏 𝑖 )).
