In-Situ Prepared Solar Light Driven Flexible Actuated Carbon Cloth Based Nanorod Photocatalyst for Selective Radical-Radical Coupling to Vinyl Sulfides.

A global challenge faced by light harvesting photocatalyst is how to promote the selective organic transformation, such as C-S bond formation via radical-radical coupling under solar light. Here, we report a two dimensional covalent organic frameworks (2D-COFs), poly (perylene-imide-benzoquinone) nanorod through in-situ condensation on flexible actuated carbon cloth (PPIBNR-FACC) to function as a light harvester material for highly selective radical-radical coupling to vinyl sulfides (i.e. C-S bond activation). Such a structure supports charge transfer from PPIBNR to FACC, which is essential for the selective radical-radical coupling. Hence, organic transformation is attaining high yields and selectivity (~99%) under solar light using in-situ prepared PPIBNR-FACC photocatalyst. The structural virtues of PPIBNR-FACC will trigger the utmost investigations into designable and versatile 2D-COFs for fine chemical synthesis.
