Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Platinum(II) polyyne polymers containing thiophene‐acceptor‐thiophene units are synthesized, and their main chain alkynes are functionalized by the formal cycloaddition–retro‐electrocyclization reaction with tetracyanoethylene (TCNE). The polymer energy levels are significantly decreased by the TCNE addition. Bulk‐heterojunction solar cells are fabricated using the TCNE‐adducted platinum(II) polyyne polymers. The use of these polymers as p‐type semiconductors in combination with n‐type fullerene derivatives indicates that the p‐type semiconducting ability decreases by approximately five to ten times after the TCNE addition. On the contrary, when the TCNE‐adducted polymers are employed as a substitute for the fullerene derivatives, the all‐polymer solar cells are initially fabricated.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh191k5rdh" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
