Three pyrene-based spirocyclic aromatic hydrocarbons (Py-SAHs) were prepared to clarify the roles of molecular segments in regulating the morphologies and photophysical properties of organic microcrystals. Due to the different supramolecular steric hindrance (SSH) effect between bulky groups and pyrene rings, distinct nanocrystal morphologies with unique photoluminescence properties were realized.
三种基于芘的螺环芳烃（Py-SAHs）被制备出来，以阐明分子片段在调控有机微晶体的形态和光物理性质中的作用。由于大体积基团和芘环之间的超分子空间位阻（SSH）效应不同，实现了具有独特光致发光性质的纳米晶体形态。
