Pyranine Based Ion‐Paired Complex as a Mechanophore in Polyurethanes [PDF]
Macromolecular Rapid Communications, 2020 AbstractA new mechanophore for polyurethane thermoplastic elastomers based on ion‐paired complexes is developed. 8‐(2‐hydroxyethoxy)pyrene‐1,3,6‐trisulfonate (HEPTS) is incorporated into polyurethanes as an end‐capper and aggregates in apolar media. Aggregation of the ionic HEPTS end groups in solution depends on concentration solvent polarity.
