Fluorescent Linear Supramolecular Polymer Based on Host-Guest Interactions

Construction of supramolecular polymers, in which functional monomer components are held together by non-covalent interactions, is considered as a promising design principle for functional materials. Linear fluorescent supramolecular polymer assembled on account of electrostatic attractions based host-guest interaction is synthesized and illustrated here. H-1 NMR was involved to ensure the structure of guest and polymer, UV-vis and fluorescent spectra were recorded to be a readout signal to investigate the assemble process of polymer. TEM and AFM measurements were carried out to confirm the homogeneous nanometer-sized molecular assembly. It shows the way to be used as remote readout fluorescent functional material in the future.
