Ratiometric Fluorescent Probe

A novel NIR ratiometric fluorescent probe HBT-GSH was developed for the selective detection of GSH over Cys and Hcy in aqueous solution. The signaling mechanism of the GSH-induced removal of an acetyl group and the switching on of ICT fluorescence was proposed.

Aqueous Solvent

The selective photooxidation of m- phenoxytoluene to m-phenoxybenzaldehyde has been investigated in the system m-phenoxytoluene/O2/titanium dioxide/non-aqueous solvent/light. In acetonitrile the conversion was found to be c. 20% with starting concentrations of m-phenoxytoluene in the range 0.05-0.5 mol dm-3. Adsorption of m-phenoxytoluene, m-phenoxybenzaldehyde or the intermediate product m-phenoxybenzyl alcohol from acetonitrile on titanium dioxide was not detectable by an equilibration/centrifugation/supernatant analysis technique. Photoemission and photoexcitation measurements, however, showed that m- phenoxytoluene and m-phenoxybenzyl alcohol, but not m-phenoxybenzaldehyde , formed charge-transfer complexes with titanium dioxide surfaces. The selectivity of the photooxidation is explained in terms of pathways involving these charge-transfer complexes.

Soluble Salt

Indium ions react with 2,2?,2"-terpyridyl in dilute alcohol or in aqueous solution forming bisterpyridyl indium salts, of which the chloride, bromide, iodide, and thiocyanate are insoluble. As thiocyanate, one part of indium per lo5 may be detected. Metals such as zinc, tin, and iron, with which indium is usually associated, interfere with the reaction. With 5-nitro-1,lO-phenanthroline, indium forms insoluble tris-(5-nitro-1,10-phenanthroline) indium salts as chloride, bromide, iodide, and thiocyanate. The reactions are of little value since the least soluble salt, the iodide, is 0.04 per cent. soluble.
