A photoreactor that generates a thin film upon rotation for efficient irradiation of solutions is described. The reactor is based around a standard piece of equipment found in most synthetic laboratories, namely, a rotary evaporator. Three different photo-oxidation reactions have been used to examine the effects of several parameters such as irradiated volume, flask size, rotation speed, and light intensity. The reactor can be operated in a semicontinuous manner, and two possible configurations are described. The thickness of the generated film and the rate of mixing under different conditions have been examined using in situ electronic absorption spectroscopy.
