Immobilization of Polymers to Surfaces by Click Reaction for Photocatalysis with Recyclability

A surface-bound photocatalyst offers advantages of reusability and recyclability with ease. While it can be immobilized by spin coating or drop-casting, a more reliable and durable method involves the formation of a self-assembled monolayer (SAM) on a suitable surface using designer molecules. In this paper, we report devising a practical, durable, and recyclable photocatalytic surface using immobilized polytriazoles of diketopyrrolopyrrole (DPP). While the SAM formation techniques were utilized for superior results, conventional coatings of polymers on surfaces were performed for comparison. Different methods confirmed efficient immobilization and high grafting density for the SAM technique. Computational models suggested favorable energy parameters for active materials. Photocatalytic studies were performed using both immobilized polymers and polymers in solution for comparison. These findings are important for understanding various physicochemical characteristics of polytriazole-functionalized surfaces.

A photocatalytic chip inspired from the photovoltaics of polymer-immobilized surfaces: self-assembly and other factors

Polymers and carbon nanomaterials for bulk heterojunction photovoltaic devices have been used to develop an efficient reusable photocatalytic chip. Interestingly, it is highly effective when the materials are self-assembled in a particular pattern at a particular concentration ratio (Movies in the ESI).
