The design and synthesis of photoactive polymeric systems are important in regard to solar energy harvesting and utilization. Although many organic photoactive systems have been developed, they suffer from their inferior long-term stability. However, Nature utilizes self-regeneration system in order to sustain photosynthesis efficiency. Here, we synthesized photoactive polymeric thin films via iterative self-assembly using reversible metal-terpyridine (M-tpy) interactions. We envisioned that the reversible M-tpy interaction can be exploited to mimic Nature’s self-repair system. In order to introduce tpy groups readily, we utilized cis-5-norbornene-exo-2,3-dicarboxylic anhydride, a norbornene derivatve, to which amine-functionalized tpy was coupled very easily. Ring-opening metathesis polymerization (ROMP) with tpy-norbornene monomers by Ru catalysts enabled the production of tpy-functionalized linear polymers and network ones. |
