<p>This invention relates to a light emitting probe complex for measuring pH consisting essentially of a polypyridine ligand having an ionizable substituent on a ring carbon atom and a transition metal ion selected from the elements of Group VIII of the Periodic Table; a light emitting probe film for measuring pH containing this probe complex in its polymer film; and a pH measurement instrument formed by fixing this probe film at the tip of an optical fiber and a pH measurement method utilizing this instrument. The present invention facilitates measurement of the pH at a microscopic part by using them.</p> |
