Owing to the capability of forming extensive hydrogen bondings and facile introduction of chirality, cyclic dipeptides (CDPs) have gained great attention as scaffolds for creation of ordered and hierarchical functional nano-architectures, and manifested diverse range of applications. Surprisingly, introduction of an intrinsically self-organized and photo-polymerizable diacetylene (DA) moiety to the CDP afforded nanotubular structures with enhanced stability and reversible thermochromism. A series of CDP-containing diacetylenes (CDP-DAs) were prepared by coupling 10,12-pentacosadiynoic acid with cyclic dipeptides. Self-assembled CDP-DAs affords nanotubular morphology via lamellar scrolling behavior, and upon UV irradiation results in the blue-colored polymeric CDP-PDA nanotubes. Interestingly, CDP-PDA nanotubes exhibits reversible thermochromism and demonstrate colorimetric reversibility for over ten consecutive cycles. |
