Through-space conjugated polymers consisting of [2.2]paracyclophane

In this review, the synthesis and fundamental properties of [2.2]paracyclophane-containing through-space conjugated polymers are introduced. By incorporating pseudo-para-, pseudo-ortho-, and pseudo-geminal-linked [2.2]paracyclophane skeletons into conjugated polymer backbones, through-space conjugated polymers consisting of stacked π-electron systems can be prepared. Recent reports in the last two years are especially focused on conjugated polymers, and the characteristic features of the through-space conjugated polymers constructed by [2.2]paracyclophane are reviewed.
