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!

Molecules: You'd better learn to live with them.

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!
