Application

This compound serves as an excellent electron-accepting building block for organic photovoltaic materials due to its strong electron-withdrawing benzothiadiazole moiety. Researchers utilize it in designing donor-acceptor polymers for bulk heterojunction solar cells. The pyridyl groups enable coordination chemistry applications, particularly in constructing luminescent MOFs for sensing applications. Its rigid planar structure also makes it suitable as a fluorescent probe in bioimaging studies.
