Abstract

We present a systematic investigation of the photophysical properties of diazocines in aqueous media. The Z-E photoconversion yields of CH2CH2- and CH2S-bridged diazocines decrease with increasing water content in acetonitrile. However, there is one exception. A CH2-NAc-bridged diazocine mostly retains its photostationary state in water (85 to 72%) because of the high quantum yields for the Z → E conversion. Moreover, it is water-soluble without further substitution and is therefore ideally suited as a photoswitch in biological (aqueous) environments.
