The peculiar co‐assembly supramolecular polymerization behavior of triphenylamine trisamide derivatives with d‐alanine (T‐ala) or glycine (T‐gly) moieties is described. Concentration‐ and temperature‐dependent circular dichroism (CD) spectroscopy revealed that the heating curves of co‐assemblies obtained at various molar ratios of T‐ala to T‐gly exhibited two distinct transition temperatures. The first transition was due to the transformation from coiled helical bundles to single helical fibers without handedness. The second was due to a change from typical elongation to nucleation. These phenomena were confirmed by solvent‐dependent decoiling of coiled helical structures and concentration‐dependent morphological analysis.

封面：奇异的基于三芳基胺的共组装超分子聚合物，在螺旋形螺旋束的形成中表现出两个转变温度（Chem.Asian J.19 / 2018）

描述了三苯胺三酰胺衍生物与d-丙氨酸（T-ala）或甘氨酸（T-gly）部分的特殊共组装超分子聚合行为。浓度和温度相关的圆二色性（CD）光谱显示，在T-ala与T-gly的各种摩尔比下获得的共组装体的加热曲线表现出两个不同的转变温度。第一次过渡是由于从螺旋状螺旋束到无螺旋性的单螺旋状纤维的转变。第二个是由于从典型的伸长到成核的变化。这些现象通过螺旋状螺旋结构的溶剂依赖性开卷和浓度依赖性的形态分析得到了证实。有关更多信息，请参见Sung Ho Jung，Jong Hwa Jung等的完整论文。就在第19期，2018页2847（：10.1002 / asia.201800961 DOI）。
