Well, when I washed the previously made red dye (what is not fluorescent at all) with some tetrahydrofuran (THF) a highly fluorescent solution was obtained what had a fluorescense almost as intense as fluorescein.

Another interesting thing was, that when I diluted this green fluorescent solution with water, the green color faded and a faint blue fluorescense could be seen under a UV lamp.

And the third thing what is quite strange, that according to the analysis what was done with this compound, the green fluorescent thing is the same as the red dye at the top of the fritted glass funnel.

SCIENCE!
