A polyolefin is functionalized with two, three, or more terminal coumarin groups. When irradiated with longer wavelength ultraviolet light (e.g., 365 nanometers), the coumarin groups cyclodimerize to form a chain-extended or crosslinked polyolefin. The cyclodimerization can be reversed by irradiation with shorter wavelength ultraviolet light (e.g., 254 nanometers). When the crosslinked polyolefin is used to form a barrier layer in a light emitting diode or a photovoltaic device, scratches in the barrier layer cleave the cyclodimer groups and can be “healed” by irradiation to reduce or remove the scratches. 2.
