A family of chiral nanographenes bearing [6]helicene units has been synthesized via the classical Scholl reaction. Inserting unit into parent nanographene skeleton can result in different structural topologies and optoelectric properties. Moreover, isolated enantiomers exhibit attractive chiroptical

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 characterized, how the solvent component affects chirality transfer their self-assembled processes is investigated in mixtures with THF H2O. The ordered assembly 11 exhibits circular dichroism response. In addition, both 11a 11b display positive photoconducting behavior.
