Straightforward synthetic routes to well-soluble and regio-defined dibenzo[g,p]chrysene derivatives

Solution‐Processable Multi‐Substituted Buckybowls: Synthesis of Diindeno(1,2,3,4‐defg:1’,2’,3’,4’‐mnop)chrysene Derivatives

“…[9] Its scalable production led us to find the regio-specific reactivity of DBC cores along with varied new products having multiple substituents. [10] Of important note was that a solution-processable DBC undertook four-fold brominations at sterically demanding fjord regions to make the core twisted with the large torsion angle of 54°: the conspicuous non-planarity arouses our interest in activation of those four bromines. [11] Herein we present a new approach with the definite attachment of functional groups onto the rim of DIC: four methoxy moieties and four alkyl groups (Figure 2).…”
