Abstract

Two spirocyclic aromatic hydrocarbon derivatives were prepared to clarify the molecular geometry effects on the regulation of the crystalline morphologies and photophysical behaviors of organic nanocrystals. Due to the different structural symmetry of a spiro-center, distinguishing nanocrystal morphologies with unique crystallization-enhanced/quenched emission was achieved.

摘要

制备了两种螺环芳烃衍生物，以阐明分子几何结构对有机纳米晶体结晶形态调控及光物理行为的影响。由于螺中心的结构对称性不同，实现了具有独特结晶增强/猝灭发射的纳米晶体形态的区分。
