- A quick check of the Aldrich catalog shows:
-
- 26,419-9 9,10-Bis(phenylethynyl)anthracene 100mg 17.10
-
- D20,500-1 9,10-Diphenylanthracene 1g 17.70
-
- The prices are a little steep, but a lot of the fluorescent materials
- are effective at very low concentrations. The diphenyl material looks
- like the thing to play with but, given the perversity of the universe,
- it probably has a tenth the fluoresence yield.
