Polymer-constrained excimer enables flexible and self-healable optoelectronic elastomer for mechanical sensor.

ABSTRACT: The development of high-performance, flexible, and self-healable optoelectronic materials is pivotal for advancing next-generation wearable technologies. In this study, we introduce nanoscale naphthyl-naphthyl microphase separation into a polyisoprene matrix, endowing olefin copolymers with exceptional mechanical properties, high flexibility, and intrinsic self-healing capabilities at room temperature without external stimuli. Notably, by employing a "polymer-constrained excimer" strategy, these copolymers exhibit remarkable photoluminescent properties, achieving an ultra-high photoluminescence quantum yield (PLQY > 98%) through the formation of naphthyl-naphthyl excimers. Experimental and theoretical analyses reveal that under the encapsulation of flexible cis-1,4-polyisoprene segments, n
