The typical errors (percent of value) of the photophysical properties are as follows: τ_S (±7%), Φ_f (±5%), Φ_isc (±15%), Φ_ic (±20%), k_f (±10%), k_isc (±20%), k_ic (±25%). The error bars for τ_S, Φ_f, and Φ_isc were determined from select repeat measurements, and those for the Φ_ic, k_f, k_isc and k_ic were obtained from propagation of errors.

The samples in water contained 5% DMF as a cosolvent.

Not examined due to low solubility.
