摘要：

合成了一种含三嗪基团的新型苝酰亚胺染料(T-PTCD), 并对其分子结构进行了确认. 考察了溶剂的极性和溶剂体积比等因素对相转移法和快速溶剂扩散法制备的T-PTCD聚集体形貌结构的影响. 结果表明, 以甲醇和三氯甲烷分别作为"不良"溶剂和"良"溶剂, 低体积比甲醇/氯仿在一定程度上有利纳米纤维的形成; 当体积比为1:4时, 采用相转移法可制备出直径大约100 nm左右, 长度为几十微米的结构规整的纳米纤维.

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.

Key words: Perylene bisimide, Nanofiber, Melamine, Phase-transfer self-assembly
