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.
通过硅烷偶联(3-氨基丙基)三甲氧基硅烷,用(P)-或(M)-1,12-二甲基苯并[c]菲接枝了尺寸为 210 纳米和 440 纳米的二氧化硅纳米粒子。手性纳米粒子在软性和硬性芳香溶剂中经超声处理后会发生解聚和聚集。
