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