Alignment of conjugated polymers by supramolecular porphyrin oligomer (2)

We proposed a novel approach for aligning and organizing of conjugated polymers by Aligners, which possess several binding sites for conjugated polymers. In this system, however, the supramolecular assemblies between Aligners and polymers are under thermodynamic control and could be destroyed by dilution or other external factors. Aligner 3, which possesses olefins as reaction sites, can bind a guest poly(phenylene-ethynylene) (poly-PPE) and organize assemblies of poly-PPEs. These assemblies were able to be immobilized by metathesis reaction.
