Fluorescence Characteristics of Phenoxy Derivatives of Pyridine

2-Chloropyridine was used as the starting material for the preparation of 2-phenoxypyridine and 2-(4methyl)phenoxypyridine. Fluorescence studies were carried out in various solvents, capped and uncapped condition at room temperature. The fluorescence study of the above compounds with respect to time was also carried out. 2-Phenoxypyridine showed the highest fluorescence peak in methanol. The fluorescence peak was observed at 321 nm, when excited at 290 nm for 2-phenoxypyridine. 2-(4-methyl)phenoxypyridine on the other hand showed the highest fluorescence peak in ethyl acetate, whereby fluorescence peak was observed at 613 nm when excited at 310 nm. The fluorescence intensity of 2Phenoxypyridine and 2-(4-methyl)phenoxypyridine decreased with time for capped condition.
