Dinaphthylene dioxide, also known as peri-xanthenoxanthene (PXX), is an organic compound used to synthesize 3,9-diphenyl-peri-xanthenoxanthene (Ph-PXX). Ph-PXX, in its soluble form, is used as organic semiconductor for thin-film transistors (TFT).{{Cite journal | doi = 10.1021/cm802826m | title = Stableperi-Xanthenoxanthene Thin-Film Transistors with Efficient Carrier Injection | year = 2009 | last1 = Kobayashi | first1 = N. | last2 = Sasaki | first2 = M. | last3 = Nomoto | first3 = K. | journal = Chemistry of Materials | volume = 21 | issue = 3 | pages = 552–556}}
