Preparation and Fluorescence Properties of Perylenediimide Nanodispersions Having a One-Dimensional π-Stacked Structure

Autor: Shohei Higuchi, Tsuyoshi Asahi, Shino Sasaki

Publikováno v: Chemphyschem : a European journal of chemical physics and physical chemistry. 18(9)

We prepared stable nanodispersions of a fluorescent perylenediimide (PDI) derivative having long alkyl chains by nanosecond laser fragmentation of its microcrystalline powder in acetonitrile (ACN). The nanoparticles had cube-like or rod shapes with a
