摘要: An intermediate compound 2, 4-bis(laurylamino)-6-(1-(2-aminoethyl)-piperazine)-1, 3, 5-triazine was prepared by stepwise nucleophilic substitution on triazine ring lauryl amine and subsequently 1-(2-aminoethyl)-piperazine. Then imidization of perylene-3, 4, 9, 10-tetracarboxylic acid dianhydride with 2,4-bis(laurylamino)-6-(1-(2-aminoethyl)-piperazine)-1, carried out to afford a novel perylene derivative bearing two melamine blocks (S2) 1, 6, 7, 12-tetra(4-tert-butyl phenoxy)-perylene-3, bisimide (S1). The hydrogen-bonding interactions between S1 S2 were investigated 1H NMR spectrum, UV/Vis spectrum fluorescence spectrum. influences the morphologies S1·S2 aggregates investigated. results show that well-defined nanofibers diameter about 100 nm can be obtained self-assembly only in CH2Cl2 solution. Based these results, guidelines for molecular design supramolecular polymer materials are presented.
