Hi I am going to publish a paper and I have made four new compounds.

The problem is one of them is practically totally non-emissive that it is even impossible for me to get its emission spectrum..

But it is awkward not to include its photophysics in the paper.

I learnt from someone that for non-emissive stuff I can write in the paper and say it is just not emissive and gathering data is not possible....

What should I do? Anyone with real experience???

You can say something like "Fluorescence was not observed under the conditions tested." You could also try to put a lower limit on the quantum yield using a reference standard, which would be based on the sensitivity of your instrument.

(Don't say it was not emissive. Everything is emissive. What matters is whether you can observe it or not.)
