[Display omitted] •We prepared one luminescent, transparent and self-healing organogel.•The organogel has excellent mechanical properties and self-healing performance.•The luminescence of organogel is stable in cold or hot environments.•And the organogel could be as one flexible sensor because of Na+ and.C20H14O72- Perovskites were widely used as the light-emission sources of luminescent elastomers in some fields. But instability, toxicity and inhomogeneity in polymers can be considered as tricky problems in the field of luminescent materials. In this paper, we have reported one luminescent organogel sensor with various admirable characters such as high elasticity, stretchable, transparent and luminescent. The organogel has a favorable self-healing performance (healing efficiency: ∼100%) benefit from borate ester bonds, hydrogen bonds and Van der Waals' forces (Debye forces). And the organogel possesses admirable mechanical properties, such as high toughness of > 1000 kJ/m3, high fracture strength of > 400 kPa, while being highly resilient (recuperative rate: 100%). In addition, the organogel can be applied as one sports sensor to monitor the states of motion thanks to Na+ and 3-oxospiro[2-benzofuran-1,9′-xanthene]-3′,6′-diolate (C20H14O72-) mobility in the organogel. This strategy mentioned above not only can enrich synthetic methods of the functional organogels, but also offered one novel elastomer that can be applied in the fields of e-skin and soft robots.
