  The photochemical cleavage of benzyl diethyl phosphates has been examined in tert-butyl alcohol, which produces the corresponding benzyl tert-butyl ether as the major solvolysis product upon direct irradiation. The multiplicity of the reactive excited state has been established as the singlet state

  The syntheses of three coumarin-caged cholesterols are reported that contain the 6-diethylaminocoumarin (DEACM), 6-bromo-7-hydroxycoumarin (BHC) and 6-bromo-7-methoxycoumarin (BMCM) photocleavable groups. Upon photolysis, the best caged derivative was found to be BHC-cholesterol whose quantum yield was determined to be 0.032 at 350 nm. (C) 2013 Elsevier Ltd. All rights reserved.

  The present invention provides methods for detecting electromagnetic energy (e.g., ultraviolet radiation) and articles suitable for use in such methods. The methods and articles can be useful for detecting sterilization or disinfection resulting from electromagnetic energy such as ultraviolet C. Detection of the sterilization or disinfection allows discontinuation of the exposure when a desired level of sterilization or disinfection has been obtained. Feedback mechanisms for controlling exposure to the energy may also be used.
