Polymeric synthetic host 2, azacrown-attached 2,6-pyridylene ethynylene polymer, was investigated for its saccharide recognition and the additive effect of triethylene tetramine–trifluoroacetic acid; heteroallosteric effects were observed on the basis of CD and UV/Vis analyses, which indicated saccharide-dependent stabilization and destabilization of helical complexes by the formation of pseudopolyrotaxanes.
研究了聚合物合成宿主 2(偶氮冠连接的 2,6-吡啶乙炔聚合物)的糖识别能力和三乙烯四胺-三氟乙酸的添加效应;根据 CD 和 UV/Vis 分析,观察到了异质柱效应,这表明通过形成伪多原烷,螺旋复合物的稳定和不稳定取决于糖。
