Given that the absorption intensity is similar to that of the free cage1 a the concentration of decorated UCNPs is estimated to be 10−5 M. It is assumed that the photochemistry of the free and anchored benzoin remains the same.
The relatively long reaction time is not a reflection of the efficiency of the photochemistry but of the fact that the1H NMR measurements require high concentrations (10−3 M) of the chromophore. At more realistic concentrations for practical applications (10−5 M) the release is five times as fast.
All solution‐state photoreactions of cage1 awere carried out using the light source from a lamp used for visualizing TLC plates at 313 nm (Spectroline ENF‐260C 1.3 mW cm−2).
Monochromatic light centred at 290 nm was generated using a fluorescence spectrometer (PTI Quantamaster) with a 3 nm slit width.
The small spot size of the light sources mean that it is critical to stir the two identical solutions of1 a[NaYF4:TmYb] in CH3CN during the irradiation to ensure that representative UV/Vis spectra are measured. Spectral changes were recorded over time until no further changes were observed at which time the photorelease was judged to be complete.
