Determining Fluorescence Quantum Yield of C60 in Toluene

For my experiment, I am trying to determine the fluorescence quantum yield of C60-fullerene in toluene (at room temperature). In order to do that, I need to have a standard sample with a valid and known fluorescence quantum yield. I have been looking for a standard sample with a known quantum yield in toluene, however, I am not sure of what to use. 


Would it be better if I used a different solvent in determining the quantum yield and if so what solvent and standard should I use.




Toluene instead of benzene can be a poor choice when H-atom abstraction by the excited state is possible. Here, you're safe.


Try to get a copy of [Fluorescence spectra and quantum yields of buckminsterfullerene (C60) in room-temperature solutions. No excitation wavelength dependence](http://dx.doi.org/10.1021/ja00067a062).


The authors apparently used 9-cyanoanthracene in toluene as a standard to determine $\Phi\_f$ of C60.


You might also want to have a look for review articles by *Dirk Guldi* from the time around 2000; I remember him giving a number of talks on C60 around that time.
