Methylated β‐cyclodextrin (Me‐β‐CD) was used to complex a free‐radical photoinitiator, 2‐hydroxy‐2‐methyl‐1‐phenylpropan‐1‐one (1), yielding the water‐soluble 1 : 1 host/guest complex 1 a. The structure of complex 1 a was verified by means of IR, UV/vis and 1H NMR spectroscopy. The influence of Me‐β...
