Three N-alkylpyridinium photosensitizers having chiral alkyl groups have been prepared by reacting 2,4,6-triphenylpyrylium tetrafluoroborate ion with (1R,2S)-(-)-norephedrine, (S)-(+)-2-(aminomethyl)pyrrolidine, and (R)-(-)-1-cyclohexylethylamine. Laser flash photolysis allows detection of the corresponding triplet excited states that are quenched by hydrogen atom donors and electron

A high-performance liquid chromatography method based on pre-column derivatization with the pyrylium salts (4-[p-(N,N-dimethylamino)phenyl]-2,6-diphenylpyrylium perchlorate (LN1) and 2,4,6-triphenylpyrylium tetrafluoroborate (L1)) has been developed for the determination of sulfide. After the reaction of sulfide ions with LN1 or L1 aiming at
