Introduction

P-1049-001 Lisboa, Portugal c ZAE Bayern, Erlangen, Germany d Skolkovo Institute of Science and Technology, Moscow, Russia e IMDEA Nanoscience, C/Faraday, 9, 28049 Cantoblanco (Madrid), Spain. Organic semiconductors have been envisioned for many disruptive technologies but have a tendency to undergo deterioration of functional properties in the presence of light and oxygen.[1,2,3,4,5] This translates into the need for careful encapsulation strategies, compromising both applicability and cost benefits.[6] Conceptually new strategies are necessary to suppress degradation reactions. Paper integral part of the final formulation.[7,8] These antioxidants are designed to induce termination steps for autoxidation by implementing tailored scavengers of radicals and other reactive oxygen species (Fig. 1). Antioxidants represent an exciting opportunity for enhancing the life span of organic electronics but remain largely unexplored in the case of organic semiconducting polymers
