<h3>Charge Transfer mediated Metal-free Photoredox Catalysis</h3>
<p><strong><span style="text-decoration: underline;">Abstract</span> :</strong></p>
<p>Charge transfer complexes are a viable route to generate radical intermediates in the excited state through an electron transfer. These Charged intermediates can either be extracted to do photocatalysis<sup>1,2</sup> or can be channelized to generate a voltage in a photovoltaic device. In catalysis, the main hurdle is to avoid the rapid back electron transfer that hampers the reactivity of Intermediates. Our lab has already established a catalytic scheme for generating reactive free radicals using a Pd<sub>6</sub>L<sub>4</sub><sup>+12</sup> octahedral supramolecule, allowing for desired product conversions<sup>3</sup>. Though highly selective, such a catalyst involves rare metals and is much less stable with different substrates. With such a background in my talk, I will discuss the synthesis of a metal-free, much simpler, catalytically robust, and highly applicable acceptor molecule based on Triazinium salts. Subsequently, the reactivity of substrates will be discussed with a deeper insight into the reaction mechanism and product selectivities.</p>
