Poly(pyridinium) salts containing calix[4]arene segments in the main chain as potential biosensors
摘要:
以生物传感为目的,通过缩聚 4,4′-(1,4-亚苯基)双(2,6-二苯基吡喃四氟硼酸盐)与钙[4]炔二胺合成了新型聚吡啶鎓盐 4,以满足生物大分子二级结构的形状适应性。研究人员通过核磁共振、傅立叶变换红外光谱、元素分析、固有粘度、凝胶渗透色谱法、差示扫描量热法、热重分析法和广角 X 射线衍射法对聚合物进行了表征。此外,还研究了聚合物的吸收光谱和光致发光(PL)光谱。此外,主要通过荧光滴定法和透射电子显微镜(TEM)研究了聚合物 4b 与荧光假单胞菌 DNA 之间的相互作用。

synthesize calix[4]arenes which are fixed in the 1,3-alternate conformation and substituted selectively by amino groups. These derivatives are useful starting materials for the attachment of various groups via amide bonds, as demonstrated by several examples, but may be converted also to ureas, imides or azomethines. Four amino groups may be attached to the narrow rim via(several) methylene groups as spacer
