Owing to their flexible, light-weight and disposable properties, paper-based electronic and sensor systems have gained much attention. Herein, we report an inkjet printable and photopolymerizable diacetylene (DA) containing microemulsion system that can be readily transferred to paper substrates using a common office inkjet printer. UV-induced polymerization afforded clean formation of polydiacetylene (PDA) supramolecules on paper and the polymer displayed a typical thermochromism. The resolution of the printed PDA images was found to be equivalent to that of conventional black ink. The randomly oriented DA in the oil phase was found to be transformed to self-assembled layered structures upon printing. The thermally promoted reversible PDA phase transition was successfully applied to a banknote to demonstrate an application to a potential counterfeit prevention method. |
