NEEDED
- Diethyl phtalate
- Sodium acetate
- TCPO : Bis(2,4,6-trichlorophenyl)oxalate
- BPEA : 9,10-Bis(phenylethynyl)anthracene (green)
Rubrene (yellow)
DPA : 9,10-Diphenylanthracene (blue)
Rhodamine B (red)
- Hydrogen peroxide
PROCEDURE
Sodium acetate (20x mg), TCPO (10x mg), and a
fluorescent dye (x mg; see below) are dissolved in
diethyl phtalate (2x ml). Addition of 30% hydrogen
peroxide (x ml) and subsequent shaking leads to
intense chemoluminescence of the corresponding
colour (the reaction lasts far over 10 hours).
Dyes:
---------- Green : BPEA
---------- Yellow : Rubrene
---------- Blue : DPA
---------- Red : Rhodamine B
