In this effort, we have prepared PDA suspensions derived from oligoethylene oxide-containing DA monomers and investigated their colorimetric responses to thermal stimulation. Depending on the DA monomers employed, the PDA supramolecules displayed different initial color changing temperatures. In general, DA monomers having larger headgroups result in the generation of colorimetrically less stable PDA supramolecules. The results described in the current investigation should provide useful information about the design of colorimetrically tunable PDA supramolecules.

带有低聚（环氧乙烷）头基的热致变色聚二乙炔超分子，可调节比色响应

在这项工作中，我们准备了衍生自含低聚环氧乙烷的DA单体的PDA悬浮液，并研究了其对热刺激的比色响应。取决于所用的DA单体，PDA超分子显示出不同的初始变色温度。通常，具有较大头基的DA单体导致比色稳定性较差的PDA超分子的产生。当前研究中描述的结果应提供有关比色可调PDA超分子设计的有用信息。
