Abstract

Silica nanoparticles with sizes of 210 and 440 nm were grafted with (P)- or (M)-1, 12-dimethylbenzo[c]phenanthrenes by silane coupling with helicenamidated (3-aminopropyl)trimethoxysilane. The chiral nanoparticles deaggregated and aggregated with sonication in soft and hard aromatic solvents.
