 Title    F Investigations on the Fluorescence of Distyrylbenzenes  
 Abstract    lu o re s z e n z -U n te rs u c h u n g e n a n D is ty ry lb e n z o le n The absorption and fluorescence of three isomeric distyrylbenzenes are investigated as function of temperature. From the fluorescence decay times and fluorescence quantum yields two classes of oligostyrylarenes can be distinguished. A decisive criterion for this classification is, whether the first excited singlet state Sj belongs to an allowed or forbidden transition S0— >Sj.
