Dibenzannulated peri-acenoacenes from anthanthrene derivatives

Abstract

A series of dibenzannulated phenyl-annulated [4,2]peri-acenoacenes have been synthesized in three straightforward steps from 4,10-dibromoanthanthrone (vat orange 3).

Industrial vat orange dyes for organic field effect transistors

“…A recent review article by Jean-François Morin summarizes in fact the entire effort made by the scientific community in the field of vat dye derivatization for organic electronic applications. 86 In the present work, we compare the above mentioned vat orange dyes that can be regarded as non-linear acenes, specifically [n,m]peri-acenoacenes, 87,88 containing additionally two ketone groups. When analyzing their molecular structures, it is instructive to compare them to that of anthraquinone, which can be regarded as consisting of two benzene rings connected by two carbonyl groups.…”
