Abstract

In this paper, we report on the self-assembly of water-soluble N,N'-di(N,N'-dimethyl-dodecane-1, 12-diamide)-perylene-3,4,9,10-tetracarboxylic diimide (PDDoAM) in formic acid and chloride salts for producing varied nano-aggregates with different optical properties. Interestingly, the self-assembly can lead to nanocubic, microsheet and "tower-like" nanostructures respectively, as demonstrated by Scanning Electron Microscopy (SEM) images. The optical properties of molecular aggregates were investigated by means of Confocal Raman Microscopy, indicating the morphologies and fluorescence of these nanomaterials are dependent on acids, acid concentrations and casting methods.

摘要

在本文中，我们报道了水溶性N，N'-二（N，N'-二甲基-十二烷-1，12-二酰胺）-苝-3，4，9，10-四羧酸二酰亚胺（PDDoAM）在甲酸和氯化物盐中的自组装过程，以制备具有不同光学性质的各种纳米聚集体。有趣的是，如扫描电子显微镜（SEM）图像所示，自组装分别可导致纳米立方体、微片和“塔状”纳米结构。通过共聚焦拉曼显微镜研究了分子聚集体的光学性质，结果表明这些纳米材料的形态和荧光取决于酸、酸浓度和浇铸方法。
