PDMS elastomers. [26] Additionally, dynamic metal-coordination bonds between Al 3+ and carboxyl of carboxyl-modified PDMS, [12,21] strong pyridyl-iron, and weak carboxamidoiron interactions, [23] etc., are also able to impart high mechanical toughness while keeping excellent self-healing property of crosslinked PDMS elastomer. However, self-healing polymers crosslinked by solely reversible noncovalent bonds are intrinsically weaker than common covalently crosslinked networks. [27] Therefore, the general yet powerful concept of introducing dynamic or permanent covalent crosslinks into a non-covalent bond crosslinked reversible network would enable the development of tough and mechanically reinforced PDMS elastomer.The deformation of self-healing elastomers under external stimuli such as mechanic force, [11,26] photo, [28][29][30] magnetic, [31] or humidity, [32] etc., can produce various electric [33] or luminescence [34][35][36] signals, hence giving accesses to fabricate comfortable epidermal devices and smart actuators. [37,38] However, most of these responsive signals were produced by the stimuli-induced deformation of the artificial devices, the dynamic visualization of external stimuli rather than the deformation of self-healing elastomers, was rarely reported. To address this issue, the colorful light emissions of luminophors, for example, the aggregation-induced emission (AIE) molecules, [39][40][41] as promising alternatives for detecting invisible information are highly desired. As one kind of AIE luminogens, 1,1,2,2-tetrakis(4-nitrophenyl)ethene (TPEN) shows no emission in their crystalline state upon heating or solvent fuming, but strong emission in amorphous fragments form. [42][43][44] Nevertheless, once quenched, the TPEN fluorescence reported so far cannot recover to its original state spontaneously without external mechanical force. Although photoluminescent feature of AIE molecules renders them intrinsic responsive to external stimuli, integrating AIE luminogens with elastic materials usually needs a complicated chemically grafting process, [37,45,46] and the resulting elastomers show weak fluorescence and lack self-healing performance.Herein, we prepared the first self-detecting and self-healing elastomer through facile blending our synthesizing self-healable PDMS elastomer with AIE molecules of TPEN. The self-healable PDMS elastomer was designed and synthesized through molecule integration of reversible multi-strength H-bonds and permanent covalent crosslink sites. The incorporation of TPEN renders the self-healable elastomer with strong on-off fluorescence that can be used for autonomous detecting mechanical damage and Most of elastomers for fabrication of comfortable epidermal devices and smart actuators produce responsive signals by the stimuli-induced deformation. Herein, a dynamic visualization of external stimuli rather than the deformation through synthesis of a self-healing poly(dimethylsiloxane) (PDMS)-based elastomer doped with aggregation-induced emission (AIE) molecules is reported....
