Abstract

2-Chloropyridine   was   used   as   the   starting   material   for   the   preparation   of   2-phenoxypyridine    and   2-(4-methyl)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 2-Phenoxypyridine and 2-(4-methyl)phenoxypyridine decreased with time for capped condition.
