The grand challenge for the efficient synthesis of known compounds and the development of new and interesting compounds using C-H functionalization reactions continues; specifically, when the compounds to be synthesized are material focused. However, C-H functionalization has been shown to be useful for the construction of new materials that are otherwise difficult to synthesize because the substrates are not compatible with the conventional reaction conditions. In addition, C-H functionalization has been demonstrated to be a very useful technique for the synthesis of materials for organic devices such as OFETs, OLEDs, and OPVs. In addition, C-H functionalization has been demonstrated to be useful in the modification of commodity products to change their properties. However, very little studies have been done to investigate the use of C-H activation reaction to prepare fluorescent dyes. As such, our group have been investigating the use of C-H activation reaction to prepare NIR fluorescent dyes for application as biosensors, and in deep tissue imaging. In this presentation, we describe our design rational for a series of a new type of water soluble NIR dye that are readily accessible by C-H activation reaction. These dyes have absorption and emission wavelengths between 700 – 1100 nm, are photostable, and have moderate to good quantum efficiency. In addition to fluorescent dyes, C-H activation has been used to prepare silole-containing polymers that show good charge mobility in OFETs. Finally, the addition of Si into vinyl substrates via a direct C-H/Si-H substitution is a very challenging feat. We have been exploring this chemistry to prepare electroactive materials and we will discuss our results in this presentation.<br/>
