Nanocrystals with crystallization-induced or enhanced emission

Abstract

In recent years, nanocrystals have attracted great research interest in a wide range of applications, such as electronics, bioimaging, and pharmaceuticals, thanks to the superior optical properties as compared to their amorphous counterparts. In this chapter, the principles of nanocrystallization methods, including top-down and bottom-up approaches, are elaborated for the synthesis of organic crystals. We specifically discuss how to use nanocrystals to improve the properties of organic fluorophores with aggregation-induced emission and crystallization-induced room temperature phosphorescence for bioimaging.
