Molecular recognition in bisurea thermoplastic elastomers studied with pyrene-based fluorescent probes and atomic force microscopy.
Fluorescence spectroscopy and atomic force microscopy (AFM) measurements using bisurea-pyrene probes show that they are randomly dispersed in the hard blocks of thermoplastic elastomers with matching bisurea groups, whereas they phase separate from polymers with non-matching or no bisurea groups.
