Abstract
In this article, the synthesis and fundamental properties of [2.2]paracyclophane-containing through-space conjugated polymers are described. By incorporating pseudo-para-, pseudo-ortho-, and pseudo-geminal-linked [2.2]paracyclophane skeletons into conjugated polymer main chains, through-space conjugated polymers comprising stacked π-electron systems can be prepared. Our recent works in this filed are especially focused on, and the characteristic features of the through-space conjugated polymers constructed by [2.2]paracyclophane are summarized. Especially, we emphasize the role of [2.2]paracyclophane moiety in the polymer backbone as well as possibility for a single molecular wire that flows energy and charges in one direction via the through-space. In addition, conjugated microporous polymers containing the [2.2]paracyclophane skeletons are also briefly introduced.
