Synthesis of crown ether-linked discotic triphenylenes

Org Lett. 2010 Feb 5;12(3):472-5. doi: 10.1021/ol902637z.

Abstract

Novel triphenylene dimers linked by a central crown ether core have been synthesized and characterized. The crown ether is most conveniently formed as a final step to permit purification and isolation of ion-free material, and extension of the protocol permits synthesis of triad structures linked though a 27-crown-9 macrocycle. The latter compounds present a new discotic motif that supports mesophase formation.
