Conjugated polymers are present in almost all organic electronic devices. However, their preparation relies on rare metal-catalyzed reactions, with poor atom economy and inducing structural defects. PhotoSynth proposes an atom-saving method based on the condensation of a diaminoPDI with a bis-aldehyde, forming a polyimine, which is then photo-cycled by visible light into a fully conjugated structure. This reaction limits waste and additives, and is versatile as any electro/opto active bis-aldehyde can be introduced into the polymer to control its properties, which will be tested in different devices. PhotoSynth opens a more efficient/eco-friendly route for the synthesis of new organic semiconductors with novel structures and properties.
