Formation and Spectral Properties of Perylene Oligomers

Abstract: We report the conditions required for the formation of perylene oligomers, which are closely related to the crystal nuclei for the formation of perylene nanocrystal. The effects of water content and perylene concentration on aggregation were studied using fluorescence and absorption spectra. The spectra indicated that fluorescent J-type perylene oligomers were formed. An aggregation number of 9, and large equilibrium constant were obtained for the reaction.
