Abstract

Monodisperse and ultrathin LaOCl nanoplates were synthesized via the thermolysis of La(CCl(3)COO)(3) in long chain amine and 1-octadecene. This single source precursor approach is simple but atomically efficient. The uniform amine-capped LaOCl nanoplates can be aligned into nanowire-like and nanorod-like superstructures, as a result of the different strengths of the interchain molecular interactions of the capping molecules during the self-assembly process of the nanoplates.

摘要

通过 La(CCl3COO)3 在长链胺和 1-十八烯中的热解反应，合成了单分散且超薄的 LaOCl 纳米板。这种单源前体方法简单但原子效率高。由于在纳米板自组装过程中封端分子的分子间相互作用强度不同，均匀的胺封端 LaOCl 纳米板可以排列成纳米线状和纳米棒状超结构。
