摘要

硼酸基两亲物是新一代的绿色表面活性剂材料,因为它们可以降解产生环境友好的硼酸。本研究描述了两种在烃链中含有酰胺键的吡啶基硼酸两亲物2-氨基十二烷基吡啶-5-硼酸钠盐(SADPB)和2-氨基十一烷基吡啶-5-硼钠盐(SADDPB)的界面性质和聚集行为。采用张力法研究了吡啶基硼酸衍生物的界面性质。利用荧光技术研究了聚集体微环境的极性和粘度。DLS测量表明,在解决方案中,SADDPB的组件尺寸大于SADPB。利用XRD技术研究了疏水尾在双层聚集体中的排列。TEM技术用于仔细检查溶液中的聚集体形态。研究结果表明,这些两亲物有望作为药物载体应用于制药工业。

Self-Assembly Study of Sodium Salt of 2-Amidodecyl Pyridine-5-Boronic Acid and Sodium Salt of 2-Amidododecyl Pyridine-5-Boronic Acid in Buffer Solution
Boronic acid based amphiphiles are new generation green surfactant materials because they degrade to produce environmentally friendly boric acid. This study describes the interfacial property as well as aggregation behaviour of two pyridine based boronic acid amphiphiles containing amide linkage in hydrocarbon chain named sodium salt of 2-amidodecyl pyridine-5-boronic acid (SADPB) and sodium salt of 2-amidododecyl pyridine-5-boronic acid (SADDPB). Tensiometry study was executed for investigation of interfacial properties of pyiridine based boronic acid derivatives. Polarity and viscosity of the microenvironment of aggregates was investigated using fluorescence technique. DLS measurement suggested size of the assemblies of SADDPB is larger than SADPB in solutions. XRD technique was employed to examine arrangement of the hydrophobic tails in the bilayer aggregates. TEM technique was utilised to scrutinize aggregate morphology in solutions. The findings showed prospect of these amphiphiles to be applicable as drug carrier in pharmaceutical industries.
