ΣΥΓΚΡΙΤΙΚΗ ΜΕΛΕΤΗ ΤΗΣ ΧΗΜΙΦΩΤΑΥΓΕΙΑΣ ΤΟΥ 2,4,5-ΤΡΙΦΑΙΝΥΛΙΜΙΔΑΖΟΛΙΟΥ (ΛΟΦΙΝΗΣ) ΚΑΙ ΤΟΥ 2-(Π-ΔΙΜΕΘΥΛΑΜΙΝΟ-ΦΑΙΝΥΛΟ-4,5-ΔΙΦΑΙΝΥΛΙΜΙΔΑΖΟΛΙΟΥ ΣΕ ΟΜ...

THE CHEMILUMINESCENCE OF 2,4,5-TRIPHENYLIMIDAZOLE (LOPHINE) AND 2-P-DIMETHYLAMINO DERIVATIVE, WAS INVESTIGATED WITH ATMOSPHERIC AND SINGLET OXYGEN, IN HOMOGENEOUS ETHANOLIC AND METHANOLIC SOLUTIONS AND IN CTAB AND SDS MICELLES. THE SOLUBILIZATION SITE IN BOTH MICELLES WAS INVESTIGATED FOR BOTH COMPOUNDS BY MEAN OF ABSORPTION AND FLUORESCENCE SPECTROSCOPY. CHEMILUMINESCENCE MICELLAR PROFILES FOR THE TWO COMPOUNDS WERE OBTAINED. THE REACTION MECHANISM OF LOPHINE IS RE-EXAMINED, SIGNIFICANTLY DIFFERENT THAN THAT OF P-DIMETHYLAMINOLOPHING. CONSIDERATION OF ACTIVATION FACTORS INDICATED A FASTER STEP IN THE CHEMILUMINESCENCE OF THE LATTER, CONTRIBUTING THUS TO THE OVERALL MECHANISM.
