Abstract

The photochemistry of thianthrene (1) in the presence of a variety of electron acceptors in acetonitrile/water has been investigated. Diffusion-limited rates of fluorescence quenching were observed on excitation of 1 (with fumaronitrile and with methyl phthalate). Alternatively, addition of 1 led to quenching of the fluorescence emission of ketones, biacetyl, and fluorenone and to the quenching of the excited triplet states of quinones such as 2, 5- ...
