A strong and tough indole-based epoxy film driven by cation–π interaction is designed, evading the trade-off between stiffness and extensibility in epoxy resins. The film with high strength, toughness and effective anti-counterfeiting properties induced by cation–π interaction is promising in the development of the fields of aerospace and electronic devices. © 2023 Society of Industrial Chemistry.
