Abstract:

A new perylene diimide dye N,N'-bis[1,3,5-triazine-2,4-bis(dodecylamino)-6-amino]hexyl-3,4,9,10-perylene tetracarboxylic diimide(T-PTCD) was synthesized and characterized. Effect of polarity and volume ratio of solvents on the morphology of aggregates prepared by phase-transfer self-assembly or rapid solvent dispersion were comparatively investigated. Well-defined nano-fiber of T-PTCD was simply fabricated by the phase-transfer crystallization between methanol(as "bad" solvent) and chloroform(as "good" solvent). Low volume ratio of methanol and chloroform facilitates the formation of nano-fiber. When the volume ratio of methanol and chloroform is 1:4, the average diameter of T-PTCD nano-fiber is ca. 100 nm and the length is about 10 μm. In addition, the morphology of aggregates prepared by rapid solvent dispersion is significantly inferior to that by phase-transfer self-assembly.
