A simple and efficient dual optical signaling chemodosimeter for toxic Hg(II)

10-Methylthioacridone, designated as acrithion, has been employed as an easily accessible chemodosimeter for the optical targeting of toxic Hg 2+ in buffered aqueous DMSO. The Hg2+-mediated desulfurization of the probe is translated into selective dual signaling of Hg2+ by means of color bleaching and fluorescence amplification while several other metal ions, including potentially competing Ag+, Cu2+ and Pb2+, afford no significant interferences even in excess concentrations.

Photochemical reactions of bianthrone and related substances

Photocleavage reactions of a wide range of ethylene compounds were investigated. Photosensitized oxygenation resulted in formation of their corresponding ketones. On the other hand, photoreaction of these substrates with elemental sulfur yielded the corresponding thioketones. Furthermore, photobehaviour of some ethylene episulfides also was studied. It could be concluded that UV-irradiation provides a rapid and effective desactivation pathway for this class of compounds.

Dication Ethers, 3. Substitution Reactions on Bis(acridinium) Ethers and 9-Trifloxyacridinium Salts by Halides, Pseudohalides and Sulfur Nucleophiles

9-Trifloxyacridinium salts 3a, b and 9,9'-oxy-bis(acridinium) salts 4a, b which are easily obtained from the 9-acridones 2a, b react readily with halides, pseudohalides and sulfur nucleophiles to give 9-substituted acridinium ions.This reaction represents an efficient alternative to the commonly used transformation of 9-chloroacridinium into other substituted acridinium salts; the two-step conversion of the carbonyl compound into a (pseudo)halide-substituted carbenium ion or into a thione may be generally applicable to ketones which can be transformed either into trifloxy carbenium ions or into dication ethers. - Keywords: Bis(acridinium) Ethers, 9-Substituted Acridinium Ions
