Question

Dark Blue: 9,10-Diphenylanthracene
Light Blue: Perylene
Green: 9,10-Bis(phenylethynyl)anthracene
Yellow: Rubrene
Orange: Rhodamine 6G

The fluorophore suspensions used listed above, I need to know which dye should work the best, glow the brightest? I know that conjugation of the molecule affects which color will be reflected, Is there a dye on this list that doesn't work as well as the others and why?

Answer 1

Green: 9,10-Bis(phenylethynyl)anthracene

9,10-Bis(phenylethynyl)anthracene (BPEA) radiates green light with greatest at 486 nm.

9,10-Bis(phenylethynyl)anthracene (BPEA) is a sweet-smelling hydrocarbon with the synthetic recipe is C30H18. It shows solid fluorescence and is utilized as a chemiluminescent fluorophore with high quantum effectiveness.

It is utilized as a part of lightsticks as a fluorophor delivering spooky green light. It is likewise utilized as a dopant for natural semiconductors in OLEDs.

The outflow wavelength can be brought down by substituting the anthracene center by incandescent lamp or alkyls. 2-ethyl and 1,2-dimethyl substituted BPEAs are additionally being used.

1-chloro-9,10-bis(phenylethynyl)anthracene radiates yellow-green light, utilized as a part of 30-moment high-force Cyalume sticks

2-chloro-9,10-bis(phenylethynyl)anthracene radiates green light, utilized as a part of 12-hour low-power Cyalume sticks
