Abstract
Abstract We synthesized π-stacked polymers by incorporating [2.2]paracyclophane units into conjugated polymer backbones and developed corresponding through-space-conjugated polymers and aromatic-ring-layered polymers. We also synthesized [2.2]paracyclophane-containing polyamidoamine (PAMAM) dendrimers and optically active polymethylenes. These polymers and dendrimers are the first well-defined and well-characterized conjugated polymers with cyclophane units in their main chain. We studied the properties of the [2.2]paracyclophane-containing through-space-conjugated polymers. We demonstrated the use of these through-space-conjugated polymers in optoelectronic applications such as an EL device. Further, we developed a synthetic strategy for new π-stacked polymers comprising layered aromatic rings on a xanthene skeleton as the scaffold. The occurrence of fluorescence resonance energy transfer from the layered cyclophanes to the end-capping aromatic moieties was verified.
