AN INNOVATIVE WAY OF OBTAINING ROOM-TEMPERATURE PHOSPHORESCENCE SIGNALS IN SOLUTION

This manuscript presents an innovative way of obtaining room temperatu re phosphorescence (RTP) in solution. For the first time, the RTP of n aphthalene derivatives have been observed in solution without using an y kind of organized media. The RTP signals are a consequence of interm olecular protection when analytes are exclusively in the presence of a heavy atom salt and sodium sulfite is employed as an oxygen scavenger to minimize RTP quenching. A rigorous study of numerous experimental and instrumental variables has been carried out. (C) 1998 Elsevier Sci ence B.V.
