Ratiometric Mechano-Fluorescent Elastomers Dually Promoted via Effective Force-Triggered Radicals and Preeminent Toughnesses/Stretchabilities by Unconventional Shuttling Dimensions of Tetraphenylethylene-Suspended [c2] Daisy Chain Rotaxanes
{{output}}
Innovative radical-type mechano-fluorescent polyurethane (PU) elastomers were developed by integrating axle- and macrocycle-exerted force modes of tetraphenylethylene (TPE)-functionalized daisy chain rotaxanes with expanded/contracted conformations into polyme... ...
