Organic Crystals with Tunable Emission Colors Based on a Single Organic Molecule and Different Molecular Packing Structures

Abstract

3(5)-(9-Anthryl)pyrazole (ANP) can be used as a building block to construct different luminescent single crystals based on hydrogen bonding and π…π stacking interactions. Five types of single crystals—obtained by controlling the molecular assembly structures—that exhibit blue, blue-green, and green emission can be obtained, two of which are shown in the figure with their corresponding structures.
