Self‐Crystallization of C₇₀ Cubes and Remarkable Enhancement of Photoluminescence

Abstract

Good solvent, poor solvent: A simple precipitation method enabled the spontaneous formation of homogeneous C70 cube crystals by self-crystallization in cavities of a good solvent (mesitylene) surrounded by a poor solvent (isopropyl alcohol, IPA; see picture). The enormously increased photoluminescence (PL) intensity of the C70 cube crystals relative to that of C70 powder was mainly attributed to the high crystallinity of the cubes.
