摘要

•Structure and color-transition behavior of 3 polydiacetylenes(PDAs) are explored.•Incorporation of aromatic head group yields reversible thermochromism.•The increase of head group size affects morphologies and packing structure of PDA.•Size of aromatic head group affects the color reversibility in high temperature region.•Sensitivity of the PDA to chemical stimuli varies with size of aromatic head group.
