Abstract

Abstract : With a variable SSH effect between bulky groups and pyrene rings, three distinct nanocrystal morphologies with unique photoluminescence properties were realized. Abstract : 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.
