Molecules: You'd better learn to live with them.
I've been thinking about chromophores a lot lately; expect the entries to reflect this.
POPOP is a laser dye and has an exceptional amount of resolvable fine structure for a relatively large molecule. See the spectrum here, from the Oregon Medical Laser Center's excellent collection of spectra and emission quantum yields. Contrast, for example, the spectra of p-quaterphenyl, p-terphenyl, and even biphenyl.
Don't be disappointed, but tomorrow's another dye!

If that title is an AD reference, then you just made my day!
Ahhhh, so sad. It was the funniest show nobody watched.

I recall making homemade scintillation cocktail in my undergrad radioisotope class - is this the same POPOP that one would mix with PPO to create the primary and secondary fluor mixture to detect low-energy beta-emitters?

Yup (PDF). PPO is actually a close relative to POPOP, too.
And yeah, it was an Arrested Development ref.

Hey, MotD. I love that some one got the title! Such fond memories of AD.

Nice reference. I enjoy the large cromophores, too!
