摘要
通过使用近红外光谱,一系列的嵌段共聚物泊洛沙姆(P85, P105 和L121)的自组装在一些离子液体(BMIMBF4, BMIMPF6 and BMIMTf2N) 中已得到研究 。超分子结构的形成已通过光学显微镜得到证实。P85、P105和L121的溶剂化程度和聚集行为取决于离子液体的咪唑环和共聚物的亲水基团之间的相互作用。将尼罗红掺入L121聚合物双分子层或者将荧光素异硫氰酸酯连接的共聚物结构上,能够观察到荧光囊泡。

摘要: The self-assembly of a series of triblock co polymers Pluronics (P85, P105 and L121) has been investigated in some ionic liquids (BMIMBF4, BMIMPF6 and BMIMTf2N) by using Near-Infrared spectroscopy. The formation of supramolecular s tructures has been confirmed by optical microscopy. The solvation degree and the aggregation behaviour of P85, P105 and L121 depend on the interactions between the imidazolium ring of the ionic liquid and the hydrophilic moiety of the copolymer. Fluorescent vesicles can be observed after the incorporation of Nile Red into the polymeric bilayer of L121 or by linking fluorescein isothiocyanate to the copolymer structure.
