摘要：

The complexation of PS-b-P4VP with a series of linear aliphatic acids in chloroform was studied. The complexes of PS-b-P4VP with all the acids except for FA can be molecularly dispersed in the solvent. The lack of the hydrocarbon tails and the higher acidity of FA make the complexed units of pyridine/FA insoluble in the low-power media, driving the self-assembly of the complexes of PS-b-P4VP/FA. The self-assembly resulted in polymeric vesicles with the P4VP and FA complex as the middle solid layer sandwiched by two solvated PS layers.
