Visible Light-Mediated Photoclick Functionalization of a Conjugated Polymer Backbone

Efficient postpolymerization functionalization of conjugated polymer backbones is generally challenging. Here, we report the first example of a conjugated polymer backbone that can be functionalized using visible light. This polymer contains a 9,10-phenanthrenequinone moiety in the conjugated backbone, which reacts with electron-rich vinyl ethers via visible light-mediated photoclick chemistry. Synthesis of the 9,10-phenanthrenequinone …
