Google turns up a number of references....including this one:

Role of synthesis for oxygen defect incorporation in crystalline rubrene

And a picture:

Packing of rubrene molecules (Carbon atoms in the tertacene backbone are coloured yellow for clarity).

Interesting article. I have never had organic chemistry, but have had more than my share of advanced mineralogy, which is basically the chemistry of silicates. This article brings back a lot of memories of the complexity of the subject.

So if there is more conductivity with the oxygen defect does it’s presence lessen the initial capturing of photons by a more pure form of the rubrene?
