摘要：
Fluorescence quenching of 3-methyl 7-hydroxyl Coumarin in prescence of the acetone is reported here. It was found that the quenching observed was of dynamic nature. It is also observed that quenching of the fluorescence of the indicator had a full reversiblity. As it has a full reversibilty, a novel optical sensor for acetone can be constructed on this quenching. (c) 2006 Elsevier B.V. All rights reserved.
