“…However, especially in multilayer organic electronic devices, for example, for printed electronics, OLED or organic photovoltaic application, too high temperatures, such as above 200 °C, during processing have to be avoided because of potential degradation of some active substances. Azides and alkynes have been involved before in crosslinking within polymers including applications such as coatings,16, 17 elastomeric materials,18 surface patterning,19, 20 hybrid multilayers,21 microstructure formation,22 and electro‐optic polymers23 and furthermore as small molecule additives in coatings,24–26 rubber materials,27 membranes,28 and electro‐optic materials 29. Thermal azide‐alkyne cycloaddition,17, 18, 23, 24 however, has only recently been applied in crosslinking and shows a great potential for further implementation in other areas of materials science.…”
