Abstract:A pair of novel chiral 1-phenylethylamine-modified twistarenes (4 and 11; compound 4 = 9,14-di-tert-butyl-7,16-diphenyl-2-(1-phenylethyl)-1H-benzo[8',9']triphenyleno[2',3':6,7]fluoreno[2,1,9-def ]isoquinoline-1,3(2H)-dione) have been synthesized and characterized, and how the solvent component affects the chirality transfer of their self-assembled processes is investigated in mixtures with THF and H 2 O. The ordered assembly of 11 exhibits circular dichroism response. In addition, both 11a and 11b display posi… Show more
A family of chiral nanographenes bearing [6]helicene
units has
been synthesized via the classical Scholl reaction. Inserting the
[6]helicene unit into the parent nanographene skeleton can result
in different structural topologies and optoelectric properties. Moreover,
the isolated enantiomers exhibit attractive chiroptical properties.

This review covers recent advances in post-functionalization of twistacenes to realize polyacenes, chiral nanographenes and their semiconductor properties, and emphasizing a promising future for constructing chiral nanotubes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
