Abstract

The facile fabrication of free-floating organic nanocrystals (ONCs) was achieved via the kinetically controlled self-assembly of simple perylene diimide building blocks in aqueous medium. The ONCs have a thin rectangular shape, with an aspect ratio that is controlled by the content of the organic cosolvent (THF). The nanocrystals were characterized in solution by cryogenic transmission electron microscopy (cryo-TEM) and small-angle X-ray scattering. The ONCs retain their structure upon drying, as was evidenced by TEM and atom force microscopy. Photophysical studies, including femtosecond transient absorption spectroscopy, revealed a distinct influence of the ONC morphology on their photonic properties (excitation energy transfer was observed only in the high-aspect ONCs). Convenient control over the structure and function of organic nanocrystals can enhance their utility in new and developed technologies.

摘要

通过在水性介质中对简单的苝二亚胺结构单元进行动力学控制的自组装，实现了自由漂浮有机纳米晶体（ONC）的简便制备。ONC呈薄矩形形状，其长宽比由有机共溶剂（THF）的含量控制。通过低温透射电子显微镜（cryo-TEM）和小角X射线散射对溶液中的纳米晶体进行了表征。TEM和原子力显微镜证明，ONC在干燥后仍保持其结构。包括飞秒瞬态吸收光谱在内的光物理研究表明，ONC形态对其光子性质有显著影响（仅在高长宽比的ONC中观察到激发能量转移）。对有机纳米晶体的结构和功能进行便捷控制可以提高它们在新技术和现有技术中的实用性。
