Polydiacetylene Sepramoiecules in Electrospira Microfibers: Fabrication, Micropatteraing, and Sensor Applications

摘要

The generation of functional supramolecular structures through the self-assembly of small molecules continues to be a significant scientific endeavour.' Molecularly assembled monomers that contain polymerizable units often serve as precursors to unique supramolecular structures that have meritorious features, for example, enhanced stability and chromogenic functions. In this regard, polydiacetylene (PDA) supramolccules, readily prepared by UV or 7 irradiation of molecularly assembled diacetylene (DA) monomers, are attractive substances. The polymer backbone of PDAs consists of alternating alkene-alkyne structures. Owing to their intriguing stress-induced chromic transition (blue to red) and nonlinear optical properties, PDAs have been extensively investigated as potential chemosensors and photonic materials.
