Persistent Fluorescence of Perylene Dyes by Steric Inhibition of Aggregation
摘要:
The control of the self-organisation of dye molecules in solution by bulky peripheral groups has been demonstrated. Consequently, fluorescent dyes could be prepared with a persistent fluorescence, even at very high concentrations because of a complete suppression of aggregation. Fluorescence quantum yields of unity were found. (C) 2000 Elsevier Science Ltd. All rights reserved.
