TpOx-Ph-p-CN

TpOx-Ph-p-CN is a UV excitable fluorescent material with a polycyclic aromatic donor-acceptor structure where the triphenoxazole core acts as a donor and the aromatic group on the two position of the oxazole (4-cyano-phenyl) act as the acceptor group. The push-pull, donor-acceptor, structure facilitates intramolecular charge transfer in the excited state that results in a 244 nm emission Stokes Shift. TpOx-Ph-p-CN is also a photo-conducting Discotic Liquid Crystalline (DLC) material with room temperature mesophase. TpOx-Ph-p-CN is designed for 355 nm and 405 nm excitation with emission at 515 nm with quantum yield of 0.32, high thermal, chemical and photostability. TpOx-Ph-p-CN has potential uses in fluorescent dye staining, organic electronic and photonics, and imaging applications.
